A detachable connector for coupling a pair of optical fibers includes two connector elements detachably connected to a connector holder. Each connector element includes a cylindrical housing, a spherical lens, a disc-shaped fiber holder, means for adjusting the axial displacement of the fiber holder in the housing, and means for adjusting the displacement of the holder perpendicular to the axis. The spherical lens is mounted in a conical bore in the housing, adjacent the fiber holder.

1. A detachable connector for coupling a pair of optical fibers comprising: two connector elements, each connector element comprising: a cylindrical housing having a reference end face and having a circularly cylindrical bore extending from the reference end face and transverse thereto, said bore having an axis and beginning with a narrow portion at the reference end face and widening with increased axial distance from the reference end face to form a conical seat and to form a rim which is parallel to the reference end face; a spherical lens accomodated in the widening portion of the bore in the housing; a disc-shaped fiber holder having a flat side and a bore for accomodating an end of an optical fiber, the bore being perpendicular to the flat side, said fiber holder being arranged in the bore of the housing to slide along the axis; means for adjusting the axial displacement of the fiber holder; means for adjusting the displacement of the fiber holder parallel to the reference end face; and a lens clamp, secured in a groove in the housing, for securing the lens in the conical seat; said detachable connector further comprising: a connector holder; and means for detachably connecting each connector element to the connector holder such that the reference end faces of the connector elements contact each other. 2. A detachable connector as claimed in claim 1, characterized in that the axial adjusting means comprises: a resilient member between the fiber holder and the rim, said resilient member forcing the fiber holder away from the rim; and an adjusting ring screwed into the bore of the housing to press the fiber holder against the resilient member. 3. A detachable connector as claimed in claim 2, characterized in that the means for adjusting the displacement of the fiber holder parallel to the reference end face comprises at least three positioning screws arranged in the housing to bear on the fiber holder.
