A hose connection system of the type consisting of a male hose connector (19) and a female hose connector (22, 42) which can be connected together, the female hose connector incorporating an end body part (23) and a sleeve (24), the sleeve being retractable along the end body part (23) to release the male hose connector (19), wherein the system also comprises a lock mechanism (30) locating around the end body part (23) and preventing the sleeve (24) from being retracted sufficiently to release the male hose connector (19). This is applicable to air brake hoses between a tractor unit (10) and a trailer, and enables the air brake hoses to be connected to the tractor unit (10) in a readily disconnectable fashion, the lock mechanism (30) preventing unauthorised disconnection. |
