Claim:
A shoe stud and receptacle combination, said shoe stud including a ground-engaging part and said stud and said receptacle are adapted to be secured together by a multi-start threaded connection comprising a screw-threaded spigot on one of said components adapted to be inserted with rotation into a screw-threaded socket on said other component, and a locking means of said components which is arranged to become interengaged at least when said spigot is fully inserted into said socket to resist unscrewing of said components, said locking means comprising at least one locking assembly, wherein the arrangement is such that the spigot and socket can begin to interengage at only one correct initial rotational position of said stud relative to said socket so as to become fully interengaged in only one correct final rotational position of said stud relative to said socket, wherein the relative number and/or position of said threads of said threaded connection and said locking assemblies determine the correct initial and final positions of said stud relative to said receptacle.
