Abstract: Disclosed is a fastener system comprising a male or stud element with a split or bifurcated head, forming two prongs, that fits inside a female or socket sleeve. Inside the socket sleeve is an internal annular ring of a smaller diameter. The stud prongs deflect radially inwardly when pushed into contact with the internal ring until the prongs pass the ring at which point they deflect radially outwardly and lock the male member within the sleeve. This locking action allows for a variety of items to be clamped together along the length of the rivet sleeve provided that at each end of the rivet there is a head of larger diameter than that of the sleeve. Each head can be replaced by any number of integrally molded items requiring a locking/mating action or where locking and rotation is desired.
