The central tube is permanently mounted on a bearing member connected to the tank. The central tube bears a first seal and a second seal. The cartridge has a collar forming an extension of the lower flange, the collar being adapted for interaction with the first seal on the central tube in order to ensure tightness between the tube and the cartridge. The second seal is adapted for interaction with the bearing member and/or the collar in order to ensure tightness between the tank and the tube.
