mounting on the end sleeve. A plug cap (31, 32) is coupled to the plug housing

removably, for closing the end opening. An access hole (31b, 32b) is formed in the plugcap, for entry of the medical instrument (14). A sealing lip (44, 44a) is disposed to projectfrom an inner surface of the plug housing, pressed by the end sleeve, for preventing fluidin the instrument channel from leaking out of the plug housing. A slit opening (44a) isformed in the sealing lip, has a slit width reduced by pressure of the end sleeve to thesealing lip, for passing the medical instrument from the access hole in a leakage-freemanner.
