1. An optical connector comprising:

  • a plug lock member for receiving an optical fiber end inserted along a center axis therein and having at least one engaging portion formed at a first angular position radially outwardly from said center axis;

    a plug which is concentrically attachable to and detachable from said plug lock member, said plug including a cylindrical outer push member having one end facing toward said plug lock member and another end opposite therefrom, said one end having at least one push portion formed concentrically and radially outwardly from said center axis, and said other end having at least one click cam formed concentrically and radially outwardly from said center axis; and

    a holding member having an inner holding portion for holding an optical fiber end along said central axis therein, at least one engagement portion formed at said first angular position radially outwardly from said center axis at one part of said holding member, and at least one cam portion formed at a second angular position radially outwardly from said center axis at another part of said holding member,wherein said engaging portion of said plug lock member and said engagement portion of said one part of said holding member, which are located at said first angular position relative to said central axis, become mated in axial locking relationship when said holding member holding said optical fiber end is inserted in said plug lock member, andwherein said plug is axially attachable on said plug lock member and said holding member inserted therein, and said push member thereof is angularly rotatable so as to rotate said push portion to said first angular position, wherein it presses said engaging portion of said plug lock member and said engagement portion of said holding member tightly in said locking relationship, and simultaneously with said angular rotation of said push member said click cam on the other end thereof is rotated to said second angular position so as to engage said cam portion on said other part of said holding member with a click locking action.
