A quick connect-disconnect fluid coupling assembly having cylindrical outer and inner coupling members, one of which is connected to a conduit and the other to a fluid conveying system. The assembly is accomplished by inserting a U-shaped locking member having a bight and two parallel legs into the outer member, which has a peripheral groove receiving the bight so that the curved portion thereof does not extend beyond the periphery. Slots in this member receive the legs, which are then locked around grooves in the inner member and the ends of the legs do not extend beyond the periphery of the outer member. The outer portion of the bight is thinner than the inner portion to permit easy insertion into, and withdrawal from, the groove of the outer member. The system may also be utilized in an assembly of three or more components, wherein two or more locking members are used.

[ What is claimed is:] [1.] A fluid coupling assembly comprising inner and outer coupling members and retaining means for interlocking said members; said inner coupling member having a generally cylindrical configuration comprising a main body portion, a reduced diameter body portion having a peripheral surface, and a first wall extending radially of and intersecting said portions, said main body portion having a peripheral groove therein; said outer coupling member being positioned over said first coupling member and having a principal cylindrical bore generally contiguous with said reduced diameter body portion, and a principal body having an enlarged diameter bore generally contiguous with said main body portion;the improvement comprisinga slot extending through a portion of said principal body of said outer member, said slot opposite and aligned with said peripheral groove on said inner member, a pair of axially aligned openings extending through said principal body of said outer member opposite to and axially aligned with said slot; said retaining means comprising a U-shaped locking member having a bight and parallel legs extending therefrom, said bight being disposed within said slot and said legs inserted within said openings, at least a portion of both said bight and said legs being inserted into said peripheral groove of said inner member to interlock said inner and outer members.
