1. A ferrule pin clamp used for a ferrule into which a guide pin is inserted along a forward-rearward direction of the ferrule, the ferrule pin clamp comprising:
two main bodies disposed in a width direction of the ferrule and each comprising a pin holder that:
holds a groove portion of the guide pin,
has a cutout that extends along an upward-downward direction of the ferrule, and
has a pair of arcs facing each other in the width direction, wherein
the forward-rearward direction, the width direction, and the upward-downward direction are orthogonal to each other; and
a connection portion that connects the main bodies at a downward side of the main bodies in the upward-downward direction, wherein
the main bodies are not connected to each other at an upward side of the main bodies in the upward-downward direction,
a diameter of the pair of arcs:
is smaller than a maximum shaft diameter of the guide pin, and
is larger than a shaft diameter of the groove portion of the guide pin,
the ferrule pin clamp has an opening that is located between the main bodies and that corresponds to a through hole of the ferrule into which an optical fiber is inserted, and
the opening opens upward along the upward-downward direction, whereas the cutout opens downward along the upward-downward direction.
