Abstract

A quick acting, self locking fastener of the spiral cam type is provided with a receptacle comprising a housing having a bottom, open top and a pair of opposed sidewalls. One of the walls is provided with a lip at the top thereof and the opposed wall is provided with a slot at its top. The closure for the housing includes a pair of biased faces which define a clip therebetween. The bottom face is provided with a slot at one end and a lip at the opposite end. A spring within the housing includes a central section that forms a cross pin for an associated stud and end sections that serve to bias the opposed sidewalls apart to secure the engagement of the sidewall'"'"'s lip and slot with those of the bottom face of the closure.
