Guide grooves 19 are formed on both side portions in the width direction, and convex portions 20 are formed on the upper side portion in the height direction along the longitudinal direction. These are for guiding the insertion / removal of the insertion portion 8 into / from the adapter 10, and therefore, even in the inner peripheral portion of the adapter 10,
A claw 21a for sliding the guide groove 19 and a guide groove 21b for sliding the convex portion 20 are formed. The adapter 10 is the same as that described in the conventional example, and the guide groove 21b is also specifically shown in FIG. 9, so refer to it. The guide groove 19 of the insertion portion 8 is partitioned by a riding portion 22 having a substantially trapezoidal cross section provided in the middle of the guide groove 19, and a hole-shaped groove 23 is formed at the base end of the guide groove 19.

In the conventional slider, as can be seen from FIG. 9, only this annular convex portion 27 is formed, which functions to improve the close contact with the slider of the hand and facilitate the movement of the slider. In addition to this, in particular, in this embodiment, a protrusion 28 is formed on the base end side of the outer peripheral portion of the slider 3 so as to protrude a predetermined length in a direction perpendicular to the longitudinal direction of the plug body 2, and this is engaged by a tool. Also tolerate. Protrusion 28
Are formed on the upper and lower side portions of the slider 3, respectively, and are formed in a rectangular parallelepiped shape having the same length as the width of the side portions.
The width w of the protrusion 28 along the longitudinal direction of the plug body 2 and the height h along the vertical direction perpendicular thereto are both 1 mm. In this way, the protrusion 28 is formed to have a minimum size that allows the engagement of the tool, and does not increase the outer size of the connector 1. Conversely speaking, the height of the annular convex portion 27 is significantly smaller than that of the protrusion portion 28, and the tool cannot be engaged.
The protrusion 28 is not formed on the side portion of the slider 3 in the width direction.

って外筒部材３０に覆われる。Here, how the connector 1 is fastened and unfastened from the adapter 10 will be described. First, at the time of fastening, the tip of the insertion portion 8 of the plug body 2 is inserted into one side of the adapter 10. This insertion may be carried by holding the hand-holding portion 9,
This is easily possible with the tools described below. When the insertion is continued, the claw 21a rides on the riding portion 22 and abuts on the tip end protruding portion 3a of the slider 3 to move the slider 3 to the base end side or rearward. When the claw 21a is further housed in the hole 23, the slider 3 returns to its original position by the urging force of the push spring 24, and the tip projection 3a covers the outside of the claw 21a so that the claw 21a is held in the hole 23. Hold on. This completes the fastening and the connector 1 is completely locked to the adapter 10. At this time, the tip protrusion 3a enters the gap 31 and is covered by the outer cylinder member 30.

Here, the distal end surface 7 of the ferrule 6 is an inclined surface that pulls downward toward the base end side as compared with upward, so that the tip end surfaces of the ferrules 6 are in surface contact with each other and the optical fibers 4 are in complete contact with each other by reversal insertion. The ferrule of another connector is provided with a hole to replace the guide pin 14, and insertion of the pin 14 into the hole achieves more accurate positioning.
The ferrules are pressed against each other by the action of the pressing spring 17.

By doing so, the holding of the claw 21a by the tip protruding portion 3a is released, and by continuing the pulling, the claw 21a comes out from the inside of the hole-shaped groove 23, and the connector 1 is separated. At this time, the stopper 33 (see FIG. 1) formed in the insertion portion 8 restricts the movement of the slider 3 and transmits the pulling force thereof to the plug body 2. In this way, at the time of disengagement, the one-action operation of only pulling the slider 3 is performed.
