The invention relates to a device comprising a water box (18) and an expansion chamber (20) for a heat exchanger for a flowing liquid. The device is moulded in one piece and has integrally moulded therewith a duct (30) whose upper end is closed by the cover of the expansion chamber (20) and whose lower end communicates, e.g. via a second duct (32), with the expansion chamber in order to form a liquid-degassing passage. The invention is particularly applicable to the radiator of a cooling circuit for an internal combustion engine in a motor vehicle.
