The valve is configured as a side-feed injector and the electrical connector (56, 57) is further away from the functional part (30) than the hydraulic connector (43, 44) of the connecting part (40).

Owing to this inner fastening connection between the module mount and the connector module, the individual connector modules can be arranged in very close lateral adjacency to each other.

The result, attained with the help of the present invention, consist in enlarging the functional capacities and operating ability of the angular joint module.

The connection device comprises a connection unit (15) forming a first channel (20) connectable to a first of said passages (8) and a second channel (21) connectable to a second of said passages (9).

The connector assembly (2) comprises a module mount (4) and a first and second connector module (6, 8).

An adapter module containing electronics for effectuating the connections is located and mounted beneath the cellular telephone cradle.
