The guiding portions connect foremost portion of front face (56) to inner face, and cooperate with end (11) of male end-unit (10) which spreads flaps from each other to guide insertion of end-unit until collar extends beyond flaps. The blocking portions connect foremost portion to remainder of front face by extending away from inner face, and cooperate with connection ring (40) by blocking flaps in closed position against aperture front edges to oppose opening during operation.
