ABSTRACT:
A releasable detent joint or coupling between telescoping cylindrical parts such as a receptacle and a tool holder held therein. The inner member is held by ball detents and a holding ring. The ring is expandable to allow release of the ball detents and separation of the parts in response to a predetermined applied torque to provide a safety release. In a simplified form of the invention, the holding ring is not expandable but release is effected merely by angular movement of the ring to a release position of the ball detents.
