The other end of the bush is located inside a sliding clamping bush, which ends with an external flange. It is characterised in that a patent shaped cap (8) is put on the clamping bush (4) and the housing end which embraces the bush. One end of the cap is locked on the housing (1), while the other end embraces the connected conduit (9). |
