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.
