ABSTRACT:
The end portions of optical fibers to be connected are accommodated in envelopes having a circularly-cylindrical outer surfaces. A connector includes a coupling sleeve with a central cavity which extends in a longitudinal direction. The central cavity is shaped as a prism having a triangular cross-section. An inscribed circle has a diameter which is smaller than the diameter of the outer surfaces of the envelopes. The walls of the central cavity are formed by free end portions of three leaf springs. The non-free ends of the leaf springs are regularly distributed around the circumference of the coupling sleeve and are secured to the wall of a housing which encloses the central cavity. The planes of the leaf springs enclose angles of approximately 60.degree. with respect to each other. When the envelopes are inserted into the central cavity, the three springs of the central cavity are independently deflected outward, so that the two outer surfaces are clamped in the central cavity with their axes aligned.
