PROBLEM TO BE SOLVED: To provide optical fibers such that even when a plurality of optical lines are used, connecting errors are prevented, the fitting forces of the optical connectors are increased, and the optical connectors can be easily connected and disconnected. SOLUTION: A plurality of turnable arms 101 are connected to each side face of one junction shell 2 and one end 101a of each arm serves as a point of application biased to the other connector connected. A projection 103 which projects in the connecting direction is provided on the side face of the one junction shell 2 and an opening which is fitted over the projection 103 with a locking ball embedded in the opening is provided in the front surface of the other optical connector.
