Abstract: A connecting element for mechanically connecting at least two components has a closure head for abutment against a first component and having a closure foot for abutment against a second component and for bracing the latter against the first component in a rotated final-mounting position. A stem portion extends between the closure head and the closure foot, which is spaced apart axially from the closure head in the longitudinal direction of the stem. The closure head has a sealing surface that extends in the longitudinal direction of the stem portion and sealingly abuts against a corresponding sealing surface of a recess in the first component. There is also described a connecting arrangement with a first component and at least one second component and a corresponding connecting element. The latter may be made from a single material component.

Abstract: Screw connection for a fixed connection of two assemblies which are mounted to each other in a variable position, using a connecting member penetrated by a screw. The connecting member is mounted between the assemblies by means of a self-cutting screw penetrating the connecting member and one of the assemblies, which screw is grooving its thread into both parts in such a way that, starting from a stable end position of the one assembly and the connecting member, the screw is adapted to be screwed into the connecting member as well as into the one assembly by means of thread grooves such that, by means of the self-cutting thread of the screw, the connecting member and the one assembly are held in a fixed position with respect to each other, and the other assembly is fastened directly to the connecting member.

Abstract: The invention relates to a U-shaped clamping piece for attachment to a panel provided with an opening, having two flat legs, connected by a yoke, with a nut part axially movably disposed between the two legs for receiving a bolt, said bolt penetrating the opening and one leg, wherein said nut part is non-rotatably held on the clamping piece by a lateral arm. The nut part is secured by its end in axially resilient manner to the leg facing away from the panel by means of a plurality of straps extending from the end of the nut part to the leg.

Abstract: The invention relates to a flexible stop buffer, particularly for cover lids, with a buffer stem and a buffer head, said buffer head being axially displaceable and being slipped over the buffer stem, wherein disposed between buffer stem and buffer head in the interior space of the latter is a buffer spring, said buffer spring pressing the buffer head away from the buffer stem, and wherein the buffer head is secured by means of locking lugs against being pulled off the buffer stem. The buffer head is provided, inside an interior space surrounded by the locking lugs, with an axial projection, from which axial projection anti-rotation elements on the buffer stem are adapted to be brought into engagement with the buffer head.

Abstract: The invention relates to a securing device for a structural component to be secured to a panel with a tubular piece inserted into a penetration in the panel, into which tubular piece is inserted a screw, said screw being supported with its head on the one end of the tubular piece and holding the structural component with its threaded part, said structural component contacting the other end of the tubular piece, said tubular piece being screwed an optional distance into the penetration for axial adjustment. The tubular piece contains a distance detector, wherein, when the tubular piece is at a distance from the structural component, said distance detector is in its starting position projecting out of said tubular piece on its side facing away from the screw head and, when the tubular piece is in contact with the structural component, said distance detector is noticeably displaced out of the tubular piece.
