Abstract: In a connection between a freshwater supply tube and the connection device, in order to avoid parts other than the parts formed by the freshwater supply tube and the connection device themselves, and in order to simplify the connecting process compared with the prior art, a supply tube is provided and contains a corrugated tube made of a plastic (PE, PA or PP) suitable for maintaining drinking water quality. An end of the corrugated tube has a substantially cylindrical shape and is coupled to the connection device. The corrugated tube is covered on the outer side with a fabric sheath of polyamide threads or fibers. The connection device is connected to the corrugated tube in a captive manner by encapsulating the cylindrical end by the plastic of the connection nozzle.
