First Claim
1. In combination, a socket and stud for an article of footwear, the stud comprising a ground-engaging portion at one end, an externally screw-threaded spigot at its other end and teeth which are spaced outward from the spigot so that an annular gap is formed between the spigot and the teeth, and the socket being an internally screw-threaded unitary moulding of a plastics material comprising a tubular portion having a radially outer surface with complementary teeth on said radially outer surface, said socket and stud arrangement being such that in an assembled condition when the spigot is screwed into the socket, a leading end of the tubular portion is received into said annular gap and the teeth of the stud surround said outer surface of the socket, the teeth of the stud and the teeth of the socket being interengaged to prevent the stud being freely unscrewed.
