Abstract: A quick connect coupler for interconnecting pressure sealed housings with pin and socket members where the socket member has a sealing bore and locking grooves. The pin member has a first rotatable ring assembly and a second rotatable ring assembly is mounted on the first ring assembly. A rotatable pawl member in the second ring assembly interlocks the socket member and the ring assemblies against axial and rotational movement. When actuated, the pawl member releases to permit relative rotation to an unlock position where the pawl member is used as a cam member to move the assemblies axially relative to one another to release the sealing connection as well as the locking interconnection.

Abstract: A locking device for a pin and socket interconnection of tubular well tool housings where a locking mechanism has a first rotatably mounted annular locking member on a second locking member on a pin end. The locking members have cooperating cam surfaces and locking segments which can be moved from a non-engaged position to our engaged position within a locking groove in a socket member. The locking members are actuated by relative rotation and also have a guide slot system for contemporaniously driving the pin end and socket member longitudinally relative to one another to a position compresssing O-rings between the pin end and socket member and a locked position of the pin end and socket member.
