ABSTRACT:
The invention relates to a connector for optical fibres, notably monomode fibres, which includes a receptacle which is accommodated in a housing sleeve. At least one connector pin is inserted into the receptacle. The connector pin is provided with a collar which is axially pressed against the end face of the receptacle by a screw cap which can be screwed onto the end of the receptacle. The receptacle is provided with a radial vent hole at the area of the end face of the inserted connector pin, which vent hole opens into a free space which extends in the axial direction between the receptacle and the housing sleeve and wherefrom air can escape to the environment. In order to achieve reliable venting and to prevent the ingress of dirt into the interior of the receptacle, without a complex manufacturing operation being required, the free space is constructed as a duct (2) which is provided in the outer surface of the receptacle (3) and which extends in the axial direction over the entire length of the receptacle (3).
