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 arm portions and a folded portion, the two arm portions facing each other and configured to open and close, the folded portion connecting proximal end parts of the two arm portions; a pressing tube that closes the two arm portions and allows the clip body to be contained therein in accordance with movement of the clip body from a distal end side toward a proximal end side; a coupling member that couples the clip body and an operation wire to each other; and an urging member that urges the coupling member relative to the pressing tube from the proximal end side toward the distal end side. The pressing tube has a latched portion, and the coupling member has a latch portion. In accordance with movement of the operation wire from the distal end side toward the proximal end side, the coupling member moves from the distal end side toward the proximal end side, the latch portion is latched to the latched portion, and the coupling member is locked to the pressing tube.
