Abstract: A device for mounting components, such as metal sheets, on one another, includes a clamp with external elastic U-shaped tongues that slide over an edge of a first component, and a section that is located between the tongues and includes an internal thread, and a screw that can engage the internal thread for mounting a second component on the first component. The screw has a thread pitch suitable for plastic materials and a correspondingly small flank angle. The internal thread has a region that is tapped, is located in, and helically extends from the central clamp section. The internal thread has more than one flight and one thread pitch for engaging the thread pitch of the screw thread.

Abstract: The invention relates to a fixing element for connecting component parts, in particular plastic paneling, to sheet-metal, in particular parts of the chassis of a motor vehicle. Said fixing element comprises a plastic body which has a base configured for insertion into a U-shaped retaining element of the component part, and a head which, when assembled, projects through an opening in the metal sheet and carries latch springs which form an acute angle in relation to the longitudinal axis of the plastic body and, when assembled, lock behind the edges of the opening in the metal sheet.

Abstract: The invention relates to a component for fastening a profile washer to a edge strip of a sheet which is surrounded by a groove in the profile washer. When assembled, a resilient metal clamp (1) surrounds with two legs (2,3) the edge strip. An intermediate layer (6,26) of a lower level of hardness is provided between the metal bracket (1) and the edge strip. The distance between the legs (2,3) lessens in the end regions (4,5) thereof, and widens again at the ends thereof.
