This rotating joint comprises two support tubes (21 and 11) which are respectively secured to a first and to a second element forming a hub (22 and 12), which have the same diameter and which, internally, are both in communication with the support tubes (21, 11). The element forming a hub (22) includes a first shaft (24) which has a central bore (241) and a hole (242) pierced in the element forming a hub (22). The element forming a hub (12) includes a second shaft (14) which has a tapped central hole (141), the shaft (14) slips into the shaft (24) and can rotate relative thereto. A screw (3) can be inserted into the hole (242) and screwed into the tapped hole (141) of the shaft (14) in order to join the two elements (12 and 22) together. A supply line can easily be slipped through the central passage (210, 110) of the support tubes (21, 11) and through the elements forming hubs (22, 12) without jamming or tension. <IMAGE>
