Abstract
The sleeve portion (1) contains a sleeve (2), the sleeve openings of which are overlain by moveable protective flaps (6, 6'). The protective flaps are placed under spring tension and are forced out of the closed position into an opened position during insertion of a plug ferrule (3) into the sleeve (2). The protective flaps have the effect that, when a plug is withdrawn out of the sleeve portion, no light can be emitted from the sleeve opening. The pivotable mounting of the protective flaps ensues between an inner sleeve housing (8) and an outer sleeve housing (9).
