A spray nozzle has a nozzle body (2) and a socket (8) for receiving a part of an insert (3). The socket (8) has a seat (9) for seating one end (10) of the insert (3), the end (10) being substantially a mirror image of the seat (9). The end (10) and seat (9) are shaped such that rotation of the insert relative to the nozzle body (2) causes the insert to be displaced out of seating arrangement. A key (17) may be used to assemble and dis-assemble the insert with respect to the nozzle body. |
