A fastener with a shank and, arranged at one end of the shank, a head intended for welding to a workpiece, has multiple detent pawls formed on the shank that extend radially outward from the shank toward the head and that are elastically resilient in the radially inward direction. On the outside, each detent pawl has an engagement recess with support surfaces. The shank has a longitudinal hole, in which is located a stud, wherein one end of the stud projects out of the longitudinal hole and forms the head for welding. Also formed on the shank is a flange that is elastically resilient in the axial direction, whose outermost edge region is located opposite the engagement recess of the detent pawls.

What is claimed is: 1. A fastener comprising:a shank for attaching a covering part to a structural workpiece, said shank having a first end and a second end,a head at the first end of the shank, said head being adapted for attachment to the workpiece,a plurality of detent pawls formed on the shank at the second end of the shank, the detent pawls extending radially outward from the shank and also extending axially from the second end toward the head at the first end of the shank, andwherein the detent pawls are elastically resilient and are adapted to be compressed about the axis of the shank in the radially inward direction until the diameter of the compressed pawls is smaller than the diameter of a mounting hole in the covering part, the pawls having on the outside an engagement recess with a radial and an axial support surface for engaging the covering part,wherein the shank has a longitudinal hole configured to receive a stud and,wherein one end of the stud projects out of the longitudinal hole and forms the head, andwherein a flange that is elastically resilient in the longitudinal direction of the shank is formed on the shank, the flange having an edge region located opposite the engagement recess of the detent pawl.
