A buckle achieves improved strap tensile strength by providing a bridge portion, about which a free end of a buckle strap is wrapped in tension, with an inwardly projecting concave surface to create a greater deformation of the strap under tension. The buckle also includes at least one strengthening cross rib on the bridge portion and a strap receiving inset with a concave shaped pocket to improve the strap tensile strength. Furthermore, the buckle includes a bendable retainer element with an inwardly directed clamping tab near its free moving end to retain a portion of the strap within the buckle.

A band clamp comprising a sleeve and a tightening mechanism that includes at least one fastener, such as a nut and bolt, as well as a reaction member which is constructed of a single piece of sheet metal. The reaction member is disposed between the end flanges of the clamp sleeve and can be shaped such that it is forcibly pressed into engagement with the underlying pipe when the clamp is tightened. The reaction member can be a separate component retained between the flanges by engagement of end portions of the reaction member with retainer ears on the flanges. Alternatively, the end flanges and reaction member can all be unitary portions of the clamp sleeve such that the complete band clamp, except for the bolt and nut, is comprised of a unitary piece of sheet metal.

A metal cable tie is disclosed. The cable tie includes an elongate metallic strap, a metallic locking head, and metallic roller means. The strap has a first end and a second end opposite the first end. The head is secured to the first end of the strap for receiving the second end of the strap. The head comprises a strap entry face, a strap exit face, and a strap-receiving aperture extending therebetween. The head further comprises a floor and a roof which diverge in the direction of the exit face. The metallic roller means lockingly engages the strap, and the head comprises retention means disposed adjacent the exit face for captively holding the roller means within the head. The roller means is movable between a threading position wherein the roller means is disposed adjacent the exit face and the retention means, and a locking position wherein the roller means is closer the entry face. The ratio of the distance from a point along a ceiling to the center of the roller means in the threading position to the diameter of the roller means is less than 1.7.

A manually-operable crimping tool for lockingly securing a seal member upon overlapped end portions of plastic strapping is provided with particular structure such that the resulting crimped seal member and overlapped end portions of the plastic strapping have an undulated configuration whereby the overlapped end portions of the plastic strapping cannot readily become loosened or disengaged with respect to each other under the influence of axially applied tensile forces. The present invention is also directed toward the particularly structured or configured seal member as well as toward the resulting sealed joint formed or defined between the seal member and the overlapped end portions of the plastic strapping.

A hose clip of the self-holding type includes a clamping ring made by circularly bending a band-shaped leaf spring. A first knob is formed by cutting off a central portion of the clamping ring at a side of its first end in a predetermined range of its length to obtain a groove-like opening and by raising the end of the clamping ring radially. The first knob includes a generally arch-shaped portion. A second knob includes a narrow portion at a side of the second end of the clamping ring, and os formed by fitting the narrow portion into the opening and passing under the arch-shaped portion of the first knob and by raising the second end of the clamping ring radially with respect to the clamping ring so that the second knob confronts the first knob. An abutment face is formed on a surface of the arch-shaped portion of the first knob opposed to a surface of the arch-shaped portion confronting the second knob. A single locking claw is formed by raising a portion defined between two spaced-apart slits each extending from one side edge of the second knob approximately to a widthwise center of the second knob. The locking claw holds the clamping ring in a spread-diameter state when engaging the abutment face, and permits the clamping ring to turn to a reduced-diameter state when disengaged from the abutment face.

A metal cable tie includes a tensioning strip and a head piece designed as a sheet metal part in the form of an elongate capsule with a tapering capsule cross section to receive a locking ball. The head piece includes at least one capsule wall being opposite the capsule bottom and designed to be elastically deflectable and provided with an opening for latching the locking ball in the latched position. A narrowed end of the capsule has an opening suitable for the insertion of a tool to push the locking ball out of the latching position.

A device for connecting at least one braid of electric cables to a connector.The device comprises on the one hand a fastening plate provided with a slot, and on the other hand, a metal band of constant thickness and width. One end of the band passes twice through the slot to form two spires around the braid. The other end is subsequently backfolded on one edge of the fastening plate and severed.

A clamping assembly is disclosed for constricting an object, such as hoses or the like. The clamping assembly includes a clamp unit and, preferably, a roll formed band. The clamp unit includes a pair of spaced, parallel shelves. A longitudinal gap is created between the two shelves for receiving portions of the band. An interior shelf of the two shelves includes locking teeth. The clamping assembly is characterized by a sidewise joining of the clamp unit and band portions. The clamping assembly also includes a worm screw for engaging other portions of the band.
