ABSTRACT:
A fastener includes a sleeve-like clamping element having a cavity extending in the direction of its longitudinal axis which accommodates a threaded stud. At least one clamping region is deformable into the cavity forming at least one clamping ramp inclined toward the longitudinal axis on an outside of the clamping element. A clamping sleeve pushed onto the clamping element in an installed state grips around the clamping element. A clamping sleeve inner surface cooperates with the clamping ramp so the clamping region reaches a clamping position deformed into the cavity to hold the threaded stud. The clamping element has a forward end flange in an installation direction. Coupling elements and mating coupling elements arranged on the flange and a clamping sleeve end facing the flange interlock in the installed state, preventing rotation between the clamping sleeve and clamping element.
