Abstract: A plug connector for a light conductor includes a plug pin having a longitudinal pin axis connected to the end of the light conductor so as to be coaxially therewith. A plug housing has a receiving bore formed therein for receiving the plug pin therein. A fixing arrangement fixes the plug pin in position in the receiving bore. This fixing arrangement includes two longitudinal grooves formed in the wall of the receiving bore so as to be disposed one behind the other and spaced a predetermined distance from each other. Two press pins are movably mounted in the housing so as to lie opposite the approximate centers of corresponding ones of the grooves. A latching member mounted on the housing is movable between first and second positions. The latching member and the housing conjointly define a space for accommodating an intermediate piece directly above the two press pins.
