The sealing piece provides a liquid-tight mounting on the mouth of a urinal comprising an opening which ends in a bottom area having two inlets each having a valve arranged in it. Each of the valves only allows liquid flow towards and into the urinal on which the mouth piece is arranged, and the valves are removable and/or replaceable. Each of the valves comprises a dome-shaped or ball-shaped leaves, or lamellar valve bodies adapted to form a non-return liquid-tight sealing against each other by their adjoining edges. The mouth piece is integrally moulded in plastics, for example for being disposable.
