ABSTRACT:
A quick-connect tubular coupling for a pair of tubes one of which has an end portion telescopically disposed within an end portion of the other. An annular cage is externally mounted on the one or inner tube in axially spaced relation to the free end of its end portion. The cage is held on the one tube against axial displacement along the latter. The end portion of the other or outer tube is flared outwardly at its free end and extends in the cage. A circular spring means is interposed between the flared end portion of the other tube and the cage and when so disposed prevents axial movement of the one tube relative to the other in telescopic disengagement direction. Between the telescoped end portions are a plurality of "O" rings that are compressed in a sealed mode to prevent leakage through the coupling.
