A breakable part ( 17 ) which is connected to the connection piece closes the channel-shaped opening. Above the membrane ( 8 ), said connection element is embodied in the form a connection piece ( 13 ) comprising an internal cone ( 14 ) and external thread ( 15 ), the membrane ( 8 ) being sealed for receiving a syringe cone shaft.
