A quick connect fluid coupling is provided for use with a fuel tank having an outwardly extending tubular and cylindrical nipple and which the nipple has a radially inwardly extending recess at a position spaced from its outer end. The coupling includes a tubular and cylindrical body which is open at each end and which is dimensioned to slidably extend over the nipple to a connected position. The body includes a plurality of elongated and circumferentially spaced slots formed radially through the body and these slots register with the nipple recess when the body is in its connected position. An elongated arcuate retainer is positioned within each slot and is radially movable between an inner locked position in which a portion of the retainer is positioned in the nipple recess, and an outer unlocked position in which the retainers are positioned outside the nipple recess thereby allowing the body to move axially with respect to the fuel tank nipple. A tubular and cylindrical locking ring is positioned coaxially around the body and is movable between an extended and a retracted position. The locked ring includes an inner cam surface which radially moves the retainers from their unlocked position to their locked position as the locking ring is moved from its retracted to its extended position.
