Abstract: An attachment device comprises a metal part obtained by cutting and folding a metal plate or sheet, and shaped as a rider designed to be fitted astride a metal support in the form of a beam or a bar. The metal part comprises a U-shaped flange having two side faces forming a jaw equipped with a series of spigots staggered along the top arms and with a pair of flexible teeth acting as springs at the ends of the bottom arms. The holding strength is enhanced, and the two flexible teeth coming into contact against the bottom face of the support enables several thicknesses of the support to be managed.

Abstract: A vibration-damping fastening element for holding pipelines having a base adapted to be anchored to a carrier plate and suspended retention means for holding the pipelines spaced from and connected to the base of two or more flexible webs, the improvement wherein said flexible connecting webs are of meander-shape.

Abstract: A two-part fastening clip for fastening a piece of longitudinal extending molding to a panel. The clip includes a bottom part having means for anchoring the bottom part in a hole in the panel and a top part having means for securing the molding to it. The bottom part has an upwardly projecting connection pin of rectangular cross-section and a pair of side pieces projecting laterally outward from two opposite sides of the upper end of the pin. Downwardly facing seat surfaces that extend in a direction perpendicular to the pin and in the longitudinal direction of the molding are provided on the lower sides of the side pieces and two outwardly and downwardly slanting slide surfaces are provided on the other two sides of the upper end of the pin.

Abstract: A retaining clip for fastening a construction part to a carrier plate, in which the retaining clip has a supporting plate that rests on the carrier plate, a clamping tab for holding the part to the clip and a compressible fastening sleeve formed of two sleeve wall halves for anchoring the clip in a hole in the carrier plate. At least one of the sleeve halves has a pair of outwardly projecting, resiliently compressible hooks that pass through the hole and then engage the plate from behind when the sleeve of the clip is pressed into the hole to hold the clip in place, and a pair of tabs adjacent the hooks that project outwardly beyond the edges of the hole on the front side of the carrier plate, so that when the tabs are squeezed together, the hooks will be released and the clip can be readily removed.
