ABSTRACT:
In a combination of shoe cleat and holder, a screw-threaded spigot (12) on the cleat is inserted with rotation into a complementary socket (18) of the holder, and has a ring of free-standing posts (34, 42) extending axially from the cleat and a ring of radially-projective teeth (26) on the holder, the rings being co-axial with the screw axis so that during at least later stages of insertion of the spigot (12) into the socket (18), on relative rotation of the rings, engagement of the teeth (26) with the posts (34, 42) causes the posts (34, 42) to deflect resiliently and engagement of the teeth (26) between the posts (34, 42) causes interengagement of the locking means.
