A coupling assembly (10) is provided wherein the ends of fluid-carrying conduit members (11,12) are sized to be hydraulically connected in a fixed releasable locking relationship utilizing first and second coupling members (25,102 and 36,106) in combination with a lock ring (43,104) and an annular spring (44). The annular spring (44) and lock ring (43, 104) are secured to the first coupling member (25,102). The first coupling member (25,102) is sized to be secured over the ends of the fluid-carrying conduit members (11,12) that have o-rings (16, 22 ) for creating a seal. The coupling members (25,102 and 38,106) are rotatable with respect to each other and have threads (34,116 and 42,140) for cooperative engagement. A locking tab (68,14 2) on the second coupling member (36,106) is sized to engage a locking recess (58,132) on the first coupling member (25, 102), thereby creating a lock between the first and second coupling members (25,102 and 36,106). The assembly provides a quick connect and quick disconnect coupling that includes a peripheral stripe (70) to provide a visual indication of the connected or disconnected status of the coupling. In addition, the coupling offers size and weight advantages over previously existing coupler assemblies.
