ABSTRACT:
A fastening device for the connection of any two members that would normally move apart under use. The fastening device consists of two components, one providing a tongue and the other a fulcrum against which the tongue bears in the fastened condition of the device. The arrangement of the components ensures that in passing between the unfastened and fastened conditions, the tongue is put into compression, the compressive stress in which acquires a value in a center-point position which is greater than that subsisting in the fastened condition of the device. Thus fastening and unfastening of the device involves moving the tongue through this center-point position.
