ABSTRACT:
A spring receptacle and its method for formation so that it can be used for removable engagement with a stud having a spiral cam slot therein to form a fastener to couple two members together. The receptacle is formed with a hollow receptacle body open on at least one end and adapted to be mounted to one of the members. An opening is in the body in alignment with an opening in the one member. A pair of opposed holes are in the body. An elongated wire of a spring material is passed through the holes and is long enough to extend across the body and outwardly therefrom through both holes. One of the body and wire is then held and the other of the body of wire is rotated a predetermined amount to cause the wire to coil within the body and form an integral coiled spring and cross bar fixed in the body. Thereafter, when the receptacle is mounted on the one member and engaged with a stud mounted on the other member and extended through the opening in the one member and into the body relative rotation between the stud and receptacle will cause the coiled spring to deflect as the cross bar follows the cam slot in the stud to the fastened position coupling the two members.
