摘要： The invention relates to an expanding rivet that comprises an expansion anchor (2) and a drive pin (3) that are captivated with one another in the pre-assembled state of the expanding rivet (1). The expansion anchor (2) is provided with an insertion hole (5) in its center which hole is adapted to the shape of the drive pin (3). The expansion anchor further comprises two support wings (12) that project laterally in opposite directions and two opposite expansion limbs (4') that project downwardly at a right angle. The pre-assembled drive pin (3) projects somewhat beyond the expansion anchor (2) while engaging with the two expansion limbs (4'). Once the drive pin (3) is driven into the expansion anchor, the expansion limbs (4') are expanded by the drive pin (3), thereby establishing a rivet connection (fig. 10). The novel expanding rivet (1) can be produced with simple means and at low costs from a metal strip. It can preferably be used where the parts to be joined by a rivet are only accessible from one side. The inventive expanding rivet is adaptable to rivet holes having different shapes and sizes and to components (23, 23' or 24, 24') having different thickness so that it has to be produced only in few sizes.

摘要： The present fixing element serves for detachably connecting sheet metal plates that are arranged in a rectangular manner in relation to each other. The inventive element consists of a receiving component that is provided with a screw thread and, from the side, can be pressed into a rectangular recess underneath the edge of the sheet metal plate and can be clamped by means of spring elements which can be pressed together in an elastic manner. The aim of the invention is to produce the fixing element as cheaply as possible. The receiving component consists of a rectangular threaded plate (1) made of metal sheet and is provided with spring legs (2) on two opposite sides. Said legs match the width of the recess (7) and are joined in a rectangular manner. Each leg (2) is provided with two spring tabs (15) which are diagonally bent outwards, symmetrical in relation to the thread axis. The edges (16) of said tabs are directed towards each other and are separated from each other by a distance (a) that at least corresponds to the width (d) of the sheet metal plates (8).
