This invention relates to a socket wrench drive extension incorporating a quick release and locking feature. The extension is used in conjunction with a ratchet drive and standard mechanic's sockets for driving threaded fasteners. The invention utilizes a longitudinal control bar which bears directly or indirectly on a detent contained in a transverse bore at the driving end of the extension. The longitudinal control bar fits a channel machined into the exterior surface of the extension and is operated through the retraction of a spring loaded collar.
