ABSTRACT:
The invention relates to a quarter-turn fastener comprising a plastics stud and a spacer, the stud having a head and shank. The shank has, at its end remote from the head, a cross-head and includes an abutment arranged to engage the side of an aperture through which the stud is mounted in use, on rotation of the stud through a quarter of a turn, to prevent further rotation in the same sense. The spacer is resilient and defines an aperture through which the shank of the stud passes in use, said spacer including a distance piece for preventing two members to be fastened together by said fastener, one situated on either side of the spacer, from coming into contact with one another adjacent said spacer.
