A clip treatment tool includes: a clip body that has two arm portions and a folded portion, the two arm portions, the folded portion connecting proximal end parts of the two arm portions； a tightening ring that functions to close the two arm portions in accordance with movement of the clip body from a distal end side toward a proximal end side； a pressing tube that has at least one opening formed in an outer surface thereof, and that allows the clip body to be contained therein in accordance with the movement of the clip body； and a coupling member that has a distal end part to which the folded portion is removably connected and a proximal end part to which a distal end part of an operation wire is fixed, the coupling member coupling the clip body and the operation wire to each other.
