An electrical and hydraulic coupling device for a system for supplying or distributing liquid to be sprayed onto a window of a vehicle. The device includes at least one tube and at least one first electrically conductive cable. The tube is delimited by a wall in which at least two liquid circulation ducts are formed and in which a heating element is embedded. The wall includes at least one recess that opens towards the outside of the tube and in which is housed all or part of the cable.
