A clip device for hemostasis includes an introducing tube (outer sheath) insertable into a body cavity. An operating wire is slidably inserted into an inner sheath, which in turn is separately advanceable and retractable within the outer sheath (introducing tube). The operating wire has a distal end portion and a retainer attached to the distal end portion of the operating wire. The clip device further includes a clip having a proximal end portion and at least three arm portions extending from the proximal end portion and provided with a tendency to open. A first retainer is attached to the distal end of the clip and is matingly received by a second retainer provided on the operating wire. A clip sliding ring is provided for closing the arm portions of the clip. Methods for delivering the clip and for causing hemostasis are also provided.
