An inserting and extracting motion of an optical plug can be easily carried out via a knob, even in a narrow space. An optical connector plug is provided with a stopper guide in a rear portion of an upper surface of a knob to which an optical plug is installed, a spring guide, an outer cover which is provided in an outer surface of the knob, and a spring which is arranged in between the stopper guide and the outer cover. In the optical connector plug, the outer cover is pressed by an optical connector adapter so as to move backward while compressing the spring, whereby a shutter is opened and the optical plug is allowed to protrude forward from the outer cover. The optical connector plug is provided with a grip portion which protrudes up and down and right and left from a rear end portion of the knob.
