ABSTRACT:
A ferrule holding device is used for holding a ferrule accommodating optical fibers therein. Two ferrules are inserted in a sleeve extending in two connector bodies of the connector to bring the optical fibers to be in aligned and close contact with each other by spring means urging the ferrules toward each other. According to the invention, the device comprises a spring urged sleeve consisting of a cylindrical body having an outer diameter somewhat smaller than an inner diameter of each the connector body. The cylindrical body is provided at plural locations with resilient curved pieces having hooks outwardly extending but depressible inwardly of an outer periphery of the cylindrical body. The connector body is formed with anchoring apertures into which the hooks of the resilient curved pieces extend so as to hold the spring urged sleeve in the connector to support the spring means urging the ferrule. A taking-off tool having taking-off pieces is inserted between the connector body and the curved pieces of the spring urged sleeve or into insert apertures formed in the connector body so as to push the curved pieces inwardly toward an axis of the connector body.
