RELEASABLE COUPLING

摘要

Apparatus (30) for attaching an elongate member (18) to a rigid member (20) , comprising a first part (40) with a body (42) for attachment to the rigid member (20) , the body (42) defining a bore (46) for slidably receiving an end of the elongate member (18) , a second part (60) having an aperture- (62) for receiving therethrough an end of the elongate member (18) , the first (40) and second (60) parts having mating screw threads (70) for releasably attaching the parts together with the aperture (62) registered with the bore (46) , a collet member (50) for engaging the elongate member (18). when received in the bore (46) , with at least one part being configured to constrict the collet member (50) as the parts are releasably attached together, and a coupling (80) , additional to the mating screw threads (70) , for providing a force to resist rotation of one part relative to the other at least when the parts are attached together.
