ABSTRACT:
A quick-release fastener device for fitment to the shank of a screw, stud or pin or the like device. The fastener is characterized by the provision of a collet member, which is composed of a number of segmental collet elements, and a retaining member which surrounds the collet member to retain the elements thereof in a cooperative relationship. The collet member is displaceable within or from the retaining member to permit separation of the collet elements one from the other and, hence, to permit quick release of the fastener from a device to which it is fitted.
