A coupling having male and female coupling members, at least one coupling lever pivotally mounted on the female coupling member and having a cam portion engageable in a groove in the male coupling member for releaseably coupling the male and female coupling members together, and at least one safety locking device for locking the coupling lever against accidental displacement from its coupling position. The safety locking device includes a reciprocally mounted locking pin or member, a spring for biasing the locking pin to a locking position where it overlies the coupling lever in its coupling position to block movement of the coupling lever to its uncoupling position, and a manually manipulatable lever member engaging the locking pin and pivotal to retract the locking pin to a lock-release position.

In a coupling, a fluid passage-defining male coupling member, a fluid passage-defining female coupling member for receiving said male coupling member, and at least one coupling and locking assembly comprising a coupling lever pivotally mounted on said female coupling member for selective pivotal movement between angularly spaced apart coupling and uncoupling positions about an axis extending transversely with respect to the longitudinal axes of said coupling members, means positioned on said lever for engaging a portion of said male member upon displacement of said lever to said coupling position to releasably couple said male and female coupling members together, said lever being swingable to its uncoupling position for uncoupling said male and female coupling members from each other and safety lock means for releasably locking said lever in its coupling position and including a support structure rigid with said female coupling member, a locking member supported by said support structure for reciprocal movement along a path extending transversely with respect to said lever, said locking member being displaceable along said path to a locking position where it overlies said coupling lever when the coupling lever is in its coupling position to block pivotal movement of said coupling lever towards its uncoupling position, said locking member further being retractable from said locking position to a release position where it releases said coupling lever for pivotal movement from its coupling position to its uncoupling position, manually manipulatable lever means supported on said support structure for pivotal movement in opposite directions, said lever means engaging said locking member and being pivotable in a pre-selected direction to displace said locking member along said path from said locking position to said release position, and biasing means acting on the assembly of said lever means and said locking member for yieldably urging said locking member to said locking position.
