A quick disconnect nozzle assembly having a nozzle body (10), an annular sealing member (20) and a nozzle tip (30) with a socket (50) in the body for receiving the tip and having a pair of chord-like lugs (51) with upstream facing camming surfaces (63, 64) for engaging downstream facing camming recesses (61) in a pair of radially extending shoulders (60) on the nozzle tip to cam the tip axially into sealing engagement with the annular sealing member as the nozzle tip is inserted in the socket and rotated therein. Preferably the socket (50) includes diametrically opposed lugs (51) and the tip has a pair of co-operating shoulders (60) and recesses (61) and at least one radially extending stop (73) adapted to engage an abutment (74) in the base of the socket when the tip (30) is rotated into proper position. The tip may include a swirl imparting vane (40) and have an outer protective sleeve (31) with longitudinal ribs (37) to facilitate rotating the tip by hand.
