A device for supplying one or more services comprises an arm (1) pivotally connected by a universal joint (5) to a mounting (7). One end of the arm (1) has a coupling unit (2) which includes coupling members (3, 4) for the or each service and which can move in part of a spherical surface centred on the mounting (7). A releasable locking means (10, 11) enables the arm to be locked relative to the mounting (7). <IMAGE> |
