Abstract
A protective flap (5) is arranged on the end of a lever arm formed as a flexible spring on the plug casing (2) of a plug (1, 1'), said protective flap covering the face and the end surfaces of an optical fiber. The lever arm is connected to the plug casing so as to be removable, and is shaped and arranged in such a way that the protective flap is pressed against the face under spring tension when in the closed position. With that, the protective flap assumes not only a screening function to guard against the escape of light, but also practically hermetically closes off the face and thus prevents dirt entering between the protective flap and the face.
