This invention relates to a light projector comprising a shutter in front of a connector socket arranged to receive the plug of an optical fiber cable insertable thereinto, and the proximal end of the plug adjacent the projector is reduced in diameter and surrounded by a heat conductor. The invention consists in that the cable plug inserted into the connector socket installed in an annular mounting and secured in its inserted position, is enflanked at its diametrically reduced extremity by several, advantageously three, cooling jaws in the form of cylindrical annular segments in a radially inwardly spring-loaded manner, which may be thrust against a spring system at an axial distance from the connector socket and its ring mounting by means of a step of a thicker section of the plug coming into contact with shoulders of the cooling jaws. The shutter of the projector may be swung out of its beam path only once the plug of the light conducting optical fiber cable has been inserted into the connector socket.
