ABSTRACT:
The invention relates to a quarter-turn fastener for fastening a panel to a support, the fastener comprising an integrally moulded plastics stud having a head and a shank. The shank extends in use through elongate slots in the panel and support and is formed by a pair of depending resilient legs each of which has at its end remote from the head a transverse flange for engaging the rear surface of the support adjacent the slot in which the stud is mounted. Each leg includes an abutment arranged to engage the side of the slot in the support or in the panel after rotation of the stud through substantially a quarter of a turn to prevent further rotation in the same sense. A resilient camming surface is also provided on each leg for engaging the side of the slot in the support during turning of the stud so that the legs have to be forced towards one another during the rotation and can then be released so that unintentional rotation of the stud from its operative position, in which the flanges of the legs abut the rear surface of the support, to its inoperative position in which the flanges can be withdrawn through the support slot, is prevented.
