Abstract
A light-conductor coupling means for coaxially connecting two optical fibres comprises two cylindrical end members, which contain the optical fibres, and a centering sleeve which receives and centers the end members with a precise fit. The centering sleeve, at its inner surface, and/or the cylindrical end members at their outer surfaces are provided with at least one spiral vent passage. The vent passage permits the air to escape when the two cylindrical end members are fitted together. The vent passage extends over the entire periphery of the inner surface so that the centricity of the arrangement is not detrimentally affected. In order to permit the cylindrical end members to be pushed together with a rapid movement, hollow cavities in the form of annular grooves in which the escaping air is temporarily compressed are also provided.
