Claim:
1. An optical connector comprising: an optical fiber cable in which an optical fiber core wire and a tensile strength material which is provided along the optical fiber core wire are covered by a sheathing; a ferrule which is fixed to an end portion of the optical fiber core wire which is exposed from the sheathing; a housing which holds the ferrule at a front thereof; a crimping sleeve which includes: a tubular portion through which the optical fiber core wire is inserted and which is let out from a rear opening in the housing; a tensile strength material holding projection which is formed on an outer circumference of the tubular portion and which is covered by the tensile strength material from which the sheathing is removed; a sheathing holding projection which is formed on the outer circumference of the tubular portion so as to lie further rearwards than the tensile strength material holding projection and which is covered by the tensile strength material and the sheathing; and a holding flange portion connected to a front end of the tubular portion; and a crimping ring which is crimped on to the tubular portion not only to thereby hold the tensile strength material between the tensile strength material holding projection and the crimping ring but also to thereby hold the tensile strength material and the sheathing between the sheathing holding projection and the crimping ring, wherein the holding flange portion of the crimping sleeve is received inside the housing, a tensile strength material cut-in groove is formed between a plurality of the tensile strength material holding projections which are provided along an axial direction of the tubular portion, and a sheathing cut-in groove having a wider groove width than that of the tensile strength material cut-in groove is formed between the tensile strength material holding projection which is provided rearwards and the sheathing holding projection.
