ABSTRACT:
A quick disconnect coupling mechanism for a collet and collet tube facilitates connection and disconnection of the two members to and from one another. In a preferred form, the collet is provided with circumferentially spaced external threaded portions which are separated by unthreaded portions. The collet tube is provided with internally threaded, circumferentially spaced mating threaded portions which are separated by unthreaded portions. The collet tube can be quickly slipped over the collet, and located at a predetermined axial position thereon, and the two components can be rotated relative to one another to cause the threads to be moved into engagement with each other. The invention provides an indicator system for providing initial alignment of the collet tube with the collet. In a independently limits axial movement of the members relative to one another beyond a preset torque limit.
