A fluid coupling assembly having a male member and a female member, the female member having an annular receiving end for receiving the male member having an annular end with an annular flange, and the female member further comprising:

• a receiving end including a plurality of annular bearings adapted to be engaged by the annular flange of the male member:
• an annular sleeve slidably mounted on the exterior of the female member and having a biasing means biasing the annular flange to the receiving end of the female member;
• a catch on the exterior of the female member juxtaposed to the sleeve when the sleeve is positioned in its normal, un-retracted position;
• and
• a latch formed as an axial slot in the sleeve extending from the inner edge of the sleeve an axial length equal to the movement of the sleeve and having a circumferential offset at its base;
• whereby the slot and offset operate to engage and lock the catch and sleeve when the sleeve is fully retracted for insertion of the male annular flange and the catch also operates to engage and lock the sleeve when the male annular flange is fully engaged with the sleeve.
