Abstract: The fastening element has a threaded part (3) and in front of it a carrier part (4) with an elastic element (5). The carrier part (4) may be a different material, such as an elastic plastic, from that of the threaded part (3) and may be joined either firmly or releasably to it, the latter for instance by a screw or detent connection. The elastic element (5) can be attached in front of the threaded part (3) with the contrary thread (6) or at some other point in frictional or detent engagement, in that at the beginning of an assembly operation, the two parts (1, 6) to be screwed together are simply inserted axially into one another. The radially outer ends of the spring tongues (5) forming the elastic element can be located on a helical line in an extension of the thread course of the threaded part (3).
