Claims

[Claims for Utility Model Registration] A connecting portion in which a ferrule with an optical connection surface formed at its tip is attached to a holder with a circular outer surface and an optical fiber is fixed to the ferrule, and a connecting portion with a circular inner surface on the circular inner surface. An optical connector plug comprising a plug body that receives, positions and holds the connection part, wherein the holder includes a locking protrusion on the circular outer surface, and the plug body extends in the axial direction from the rear end. an axial groove in which the locking protrusion can be inserted; and a groove connected to an intermediate portion of the axial groove and extending in the circumferential direction, which allows the locking protrusion to be moved in the circumferential direction from the axial groove. a locking groove that locks one side of the locking protrusion at a predetermined axial position and locks the locking protrusion at a predetermined axial position; The other end is fixed and extends to the connecting portion with the locking groove to form a cantilever beam having spring properties in the radial direction, and has an inclined surface that can come into contact with the locking protrusion on the inner diameter side of the other end. and a locking piece having a locking surface for locking the other side surface of the locking protrusion.
