The supply and discharge hoses form an extruded profile moulding. The mantle of the supply (6) and of the discharge-hose (9) run close to each other, and are connected with each other over the common length by a separation web (12). This hose moulding (13) carries a groove (14), open towards the outside, in which the electric current supply cable is laid. The cable can be detached as required.
