The optical plug includes a ferule, adapter housing, a plug body, a compression coil spring and a compression bonding sleeve. The plug body includes a projecting portion and an extending portion which is provided with a plurality of annular grooves. The compression bonding sleeve includes a crimp portion and a support portion. According to the present invention, the diameter of the crimp portion is uniformly narrowed so that the crimp portion compression-bonds the high tensile strength wires to the annular grooves of the extending portion. Accordingly, it is possible to maintain the deformation of the crimp portion within the limit of its plastic deformation and hence, the occurrence of cracks and rupture can be prevented, so that the optical plug can be miniaturized. Further, it is possible to mount the optical fiber cable to the optical plug at a low cost.
