Patent ID: 7658420

Claim:
A quick connect coupling comprising: first and second coupling parts connectable to each other for enabling fluid communication between respective fluid flow passages of the first and second parts; an interlock mechanism for interlocking the coupling parts in a connected state, the interlock mechanism including a catch associated with one of the coupling parts, and a latch member associated with the other of the coupling parts, the latch member configured to interlock with the catch when the first and second coupling parts are connected to thereby restrict disconnection of the coupling parts; and a rotatable release member on one of the first or second coupling parts rotatable between a first position allowing the latch member to interlock with the catch and a second position holding the latch member in an unlatching position to allow separation of the first and second coupling parts; wherein the rotatable release member further includes a lock member, the lock member configured to restrict movement of the latch member out of engagement with the catch; and wherein the lock member has a lock member catch configured to engage a surface of the latch member when the rotatable release member is in the first position, the lock member catch configured to restrict rotation of the rotatable release member from the first position to the second position.
