-7- ABSTRACT: "Connector for coupling optical fibres". The end portions (5) of the optical fibres (7) to be connected are accommodated in envelopes (9) having a circular-cylindrical outer surface (11). The connector includes a coupling sleeve (3) with a central cavity (19) which extends in its longitudinal direction and which is shaped as a prism having a triangular cross- section whose inscribed circle (23) has a diameter which is smaller than the diameter of the outer surface (11). The walls of the central cavity are formed by free end portions of three leaf springs (21) whose non-free ends are regular- ly distributed around the circumference of the coupling sleeve and secured to the wall of a housing (17) which encloses the central cavity, the planes of said leaf springs enclosing angles of approximately 60° with respect to each other. When the envelopes (9) are inserted, the three springs (21) of the central cavity (19) are indepen- dently deflected outwards, so that the two outer surfaces (11) are clamped in the central cavity with their axes aligned.
