CLIPPING TOOL

Provided is a clip treatment tool with which it is possible to, after a clip has been once applied, reliably maintain the applied state, and it is possible to remove the clip, which is placed in a living body, at any desirable timing. A clip treatment tool includes a clip body that has two clip pieces, the two clip pieces each having a body portion and an arm portion, the body portion having a fixing hole formed on a proximal end side and a movement hole formed on a distal end side relative to the fixing hole, the movement hole extending so as to be inclined from a side part in a width direction of the body portion on the proximal end side toward a middle in the width direction of the body portion on the distal end side; a container tube that contains the body portions of the two clip pieces therein; a stopper that extends through the fixing holes of the two clip pieces and that is attached to the clip body; and a fixing pin that extends through the movement holes of the two clip pieces and whose both end portions are fixed to positions in the container tube that face each other.
