ABSTRACT:
A novel quick-disconnect coupling is disclosed comprising a tubular member and a sleeve member sealingly receiving the tubular member therein. The coupling members each attachable to a hose end provide quick connect and disconnect of the hoses to one another. The tubular member is generally conical in shape having a larger diameter at its distal end and a smaller diameter at its proximal end. The sleeve member includes a plurality of axially extending fingers which, after the members are joined, are forced radially inward against the converging conical surface of the tubular member by an encircling collar thereby securing the sleeve member to the tubular member until the collar is retracted.
