Abstract
A fastener for a closure. The fastener has a friction joint which couples first (10) and second (23) elements such that rotational movement there between can occur. The friction joint has a head fastener (28) and a sleeve (24) to which an end load is applied upon axial movement of the fastening taking place during coupling of the first and second elements (10, 23). This end load causes the sleeve (24) to collapse. The fastener has a wedge element (37) mounted for rectilinear movement in a direction substantially transversed to the axis of rotational movement of the friction joint. A drive arrangement (35) couples the wedge element (37) with the second element (23) such that rotation of the second element (23) is translated into the rectilinear movement of the wedge element (37). A removable handle (44) couples via fingers (49) to second element (23).
