A hose connector assembly for connecting a hose to a port of a pressurized fluid system, the system including a socket and an adapter tube in fluid communication, with an end portion of the socket adapted to be connected to a port and having a receiving opening. The adapter tube has a plug-in end portion to be pushed into the receiving opening which is adapted to cooperate with the plug-in end portion to form a plug-in connection mechanism. The adapter tube has a hose connector end fitting adapted to be received in, hold and retain a hose end portion. Complementary locking surfaces of the receiving opening and plug-in end portion are engaged when the plug-in end portion is connected by the plug-in connection mechanism to the socket to lock the adapter tube with respect to the socket against rotation about the longitudinal axis of the adapter tube within the socket.

A water transferring device is provided and comprises a body having a water passage chamber, a first water inlet joint having a first water inlet passage and connected to the body, and a water outlet joint having an outer water passage and an inner water passage. The first water inlet joint and the water outlet joint enable the inner water passage to be in communication with the first water inlet passage. The water passage chamber is in communication with the outer water passage. At least one of the first water inlet joint or the water outlet joint comprises a connection structure connected to the body and enabling the at least one of the first water inlet joint or the water outlet joint to be at least rotated for a specific angle around an axis of the at least one of the first water inlet joint or the water outlet joint.

A connector is provided comprising a hollow connector body having a central aperture and a hollow tube that is rotatable within the central aperture without rotating the hollow connector body.
