First Claim
1. A clip comprising a self-opening clip body having a clipping part at a tip and equipped with a twin-arm part extending from a basal part, and a securing ring, wherein the self-opening clip body has a first concave part on a clip basal end, and a second concave part between the first concave part and a clip tip part, respectively, and the securing ring is mounted in the first concave part and, at the same time, sliding-moved with an external force from a mounting position in a first concave part to be mounted in the second concave part, which is used as a treating equipment for an endoscope which closes a clipping part of a tip of the clip body.

Abstract
A clipping instrument for biological tissues equipped with an outer tube which can be inserted into a biological cavity, an operating member freely passed through the outer tube, an operating wire freely passed though the operating member, a self-opening holder which can be opened and closed by the action of the operating member attached to the edge of the operating wire, and a self-opening clop having a clipping member for clopping a biological tissue which is attached to the edge of the holder in a detachable manner by opening/closing the holder. Using this clopping instrument, a lesion site can be surely clipped over a long period of time in ligating a breeding site in a biological tissue, stitching a laceration, making in excision of a mucosal tissue and so on with an endoscope.
