1. An optical fiber connector comprising:

  • an optical fiber plug, said plug including;

    a ferrule for fixing an optical fiber on a center axis thereof said ferrule having a terminal tip;

    a spring member positioned coaxially with said ferrule and along an outer periphery of the ferrule;

    a slipout-preventing member fixed to the ferrule for preventing said spring member from slipping out;

    a first housing for accommodating the ferrule, the spring member and the slipout-preventing member, said first housing being provided with a pair of parallel extensions, each extending toward said terminal tip of the ferrule along an opposite side periphery of the ferrule, and a pawl protruding from a tip of each of said extensions toward the center axis of the ferrule; and

    a second housing for accommodating said first housing and slidable a predetermined amount in a direction parallel to the center axis of the ferrule in contact with an outer periphery of said first housing, said second housing being so configured that said pair of parallel extensions snugly fit into said second housing and are prevented from expanding from each other at a position where said second housing is moved forward along said pair of parallel extensions;

    an adapter for receiving said optical fiber plug, said adapter including;

    a block provided with a cylindrical bore for receiving the ferrule, said block having a pair of parallel outer side surfaces which are disposed symmetrically about a center axis of said bore, and a recess provided in a part of each of said side surfaces;

    the plug and the adapter being connected by mating the recesses of said block of the adapter with the respective pawls of the first housing while inserting the tip of the ferrule into the cylindrical bore of the adapter and, then, sliding the second housing to said position.
