ABSTRACT:
A quick connect coupling is provided for quick and easy connection or disconnection of a pair of conduits, such as ordinary garden hose. The coupling comprises interlocking tubular male and female fittings adapted for respective connection to a pair of hoses, wherein the male fitting includes a male member with an external circumferential groove positioned for axial alignment with a generally opposed pair of arcuate slots in a female member on the female fitting. A generally C-shaped retainer is carried about the female member and includes a pair of locking arms projecting from a central base generally through the arcuate slots with their free ends engaging radially oriented cam surfaces on the female member. The locking arms are normally biased radially toward each other to position their radially inner edges within the circumferential groove in the male member to lock the coupling together. However, the locking arms are movable radially away from each other by pushing radially inwardly on the central base to move the free ends of the locking arms radially outwardly along the cam surfaces thereby displacing the arms from the circumferential groove to unlock the coupling.
