Abstract
A fastener has a receptacle (1) and a stud (10), the receptacle (1) having a pair of clip-like legs (6) the ends of which engage in grooves (16) in the shank of the stud (10). Each of the legs (6) has a plurality of formations (8) on its inner surface, the formations being shaped so as to engage the wedge-shaped lead-in portion (14) of the stud as it is inserted into the receptacle so as to rotate the stud into a position in which the legs (6) of the receptacle must engage in opposed grooves (16) on the shank of the stud.
