The connector comprises two coupling elements (1) in each of which end parts of light conducting fibres (9) are secured mutually in parallel beside each other in such a manner that the centers of their end faces (15) are situated on one line (17) in an end face (19) of the coupling element (1). The connector further comprises a connector housing (25) for receiving the two coupling elements (1). Each coupling element (1) has a cylindrical outer surface (20) the axis of which coincides with the axis of the light conducting core of one of the fibre end parts (9) secured therein (preferably the central one) and which is capable of cooperating with a centring member (27) of the connector housing (25). Each coupling element furthermore has an orientation element (23) which is capable of cooperating with an orientation member (29) of the connector housing (25). As a result of this the cylindrical outer surfaces (20) of the two coupling elements (1) are located with their axes in the elongation of each other and the lines (17) on which the centers of the fibre end faces (15) are located are mutually parallel. As a result of this an optimal coupling between each pair of light conducting fibres (9) is ensured.
