The invention relates to a fastening element that is suited for fastening a component to a supporting part (3). Said fastening element is comprised of a holding part (1) for the component to be fastened and of an anchor foot (2), with which the fastening element can be anchored in a through-hole of the supporting part (3). The anchor foot (2) comprises a shank (5), which perpendicularly projects from the holding part (1), and comprises at least two opposite spring arms (4), whose ends are joined to the shank end (6), which spread in the direction of the holding part (1), and whose outer surfaces are provided with opposite contact surfaces (14) which are set back by steps (13). When inserting the anchor foot (2) into the hole in the supporting part (3), these contact surfaces (14) rest against the wall of the hole in a spring-like manner while the steps (13) simultaneously engage behind the edge of the hole. The fastening element is characterized in that opposite contact surfaces (12, 14), which are radially set back by steps (11, 13), are arranged in pairs on the conically spreading spring arms (4) at different heights that correspond to the diameter of different width holes in the supporting part (3). The curvature of these contact surfaces follows that of the respective hole wall (15). The shank (5) comprises, at the same heights, however, while being offset by 90° with regard to the spring arms (4), contact surfaces (9, 10), which correspond to the diameter of the same different width holes in the supporting part (3) and whose curvature follows that of the respective hole wall (15). These contact surfaces (9, 10) rest against the relevant hole wall (15) when inserting the anchor foot (2) into the hole of the supporting part (3).

The retaining spring is used for detachably connecting two components (1) and (2) which can be moved against each other. The retaining spring comprises a retaining plate (3) which can be placed on one component (1) and a detent spring (4) which is moveably guided on the retaining plate (3) between a detent position and a loosened position in the direction of attachment. The detent spring (4) is provided with a detent edge for engagement with a detent projection (7) which is provided on the other component (2). A slanted insert limb (6) used to raise the detent spring (4) when the displaceable component is advanced is arranged upstream from the detent edge(5) in the direction of attachment. In order to connect and detach the two components (1) and (2) with greater ease, even when space is lacking in the area immediately surrounding the connection points, the detent spring (4) which is embodied as a separate element is maintained in a position of engagement on the retaining plate (3) by detent means (11,12) acting against the resistance of the spring in the direction of attachment.

The invention relates to a heatable windscreen washer nozzle which is fastened to the windscreen wiper of a motor vehicle. The washer nozzle consists of a housing provided with a connecting element (2). The connecting element (2) is joined to a splash water hose (19) which can be electrically heated by integrated wires (22) or a wire fabric. The ends (23) of the heating wires (22) are electrically bypassed just in front of the end of the hose (24). The housing (1) is also provided with a chamber which accommodates a nozzle body (6) and contains a heating plate (28) disposed above the nozzle body(6), in addition to a cover (8) used to seal the chamber. The nozzle body (6) is embodied as a flat chip wherein several channel ducts are guided from a central water through-flow inlet (25) in an outward direction in the form of a fan.A rib (29) is formed on the edge (32) of the heating plate (28), fully covering the surface of the nozzle chip. The rib extends into the connecting element (2) in such a way that the ends (23) of the heating wires (22) extend over the rib (29) of the heating plate (28) in a contactless manner when the heated splash water hose (19) is placed on the connecting element (2). The heat generated by the heating wires is thus advantageously transmitted to the heating plate without coming into direct contact with the rib. The warmed heating plate can thus directly emit heat to the splash water as far as the end of the channel ducts, resulting in optimum heating of said splash water.

Disclosed is a novel method for producing connection systems consisting of at least two plastic parts which are functionally movable relative to each other in a rotating manner. According to said method, the inner (1; 15) of the two parts (1, 2; 15, 16) that are rotationally movable relative to each other is first cast or injected from a plastic material in a mold, whereupon the outer (2;16) of the two parts (1, 2; 15, 16) that are rotationally movable relative to each other is cast or injected from a different plastic material over the inner part (1; 15). The inner part (1; 15) or at least one portion thereof is used as a core for the outer part, the two materials which are used for the inner and the outer part not being adhesive or sticking to each other. Such a connection system is provided with a pin part (2) comprising a pin (11), and an anchor part (1) comprising claws (5) that are forced apart by twisting the pin (11), for example. The pin part (2) is used as a core for the anchor part (1) during the production process.

The invention relates to a covering device for covering a mounting recess in a cover strip of a vehicle roof. Mounting recesses of this type are, for example, provided for fastening the feet of a roof luggage carrier. The covering device is comprised of an insertion part (1), which can be positioned inside the cover strip (3), and of a hinged cover (2), which is mounted in bearing shells (7) in a manner that enables it to pivot about an axis in the longitudinal direction of the strip and which fills the recess (4) when in a closed position. Said hinged cover comprises both bearing journals (6), which are shaped thereon at both ends, as well as detent journals (11), which can be locked in an open and closed position by means of spring elements (12). These spring elements are shaped onto the insertion part (1) and act upon the detent journals (11). The hinged cover (2), when in an open position, enables an unhindered access to the recess (4) by virtue of the fact that the bearing journals (6) and detent journals (11) are shaped onto the hinged cover (2) via a U-shaped element (5), which is dimensioned in such a manner that the edge (8) of the recess (4) projects into the open space (9) of the element (5) when the hinged cover (2) is open.

The inventive plastic fixing element comprises a base part (3) for inserting into a longitudinal cavity (4) of a carrier plate (20). The base part (3) consists of a head (5), whose shape corresponds to the edge (6) of the longitudinal cavity (4) and a shaft (7), which is adapted to the width of said cavity (4). Once the head (5) has been inserted, the base part can be locked in the longitudinal cavity (4) by means of a quarter-rotation and the elastic deformation of the shaft (7). To prevent the base part (3) from working loose in the longitudinal cavity, the shaft (7) has a central strut (10) of the same width as the longitudinal cavity (4), which connects the head (5) to the base part (1) of the fixing element. A respective limb (12) is formed at a right-angle and in opposing directions on each edge (11) of said strut, in such a way that the limbs (12) are bent elastically towards the central strut (10) by the edge (6) of the longitudinal cavity (4) during the rotation of the shaft (7) and after a quarter-rotation return to their original position as a result of the elastic restoring force of the plastic, thus preventing a rotation in the opposite direction.
