摘要

The system has a body forming a plug (3), and a siphon (1) connected to evacuation of sanitary appliance. The plug has a drain section at its lower part on which a thread (6) is situated to cooperate with a thread (4) of the siphon. The siphon has a cylindrical part (12) and a conduit (18) communicating with each other by the bottom of a part forming a bowl (8). A joint (2) seals between the section and a co-operating part of the siphon. The section has flexible tabs (7) deformed during the installation of the siphon on the plug to exceed an abutment (5) positioned opposite to siphon elements.
