a first arm;
a second arm; and
a tube including a through hole, the tube being configured to accommodate at least a part of the first arm and the second arm;
a sheath;
a wire located in the sheath;
a connector connecting the wire to the clip, and
a deformable leg engaging the sheath with the clip, the deformable leg including first and second legs, wherein:
at least one of the first leg and the second leg has a first terminal end that is configured to be inserted into the through hole, a second terminal end located opposite the first terminal end, and an intermediate section located between the first terminal end and the second terminal end, wherein:
the intermediate section is located radially inward of an inner surface of a distal end of the sheath,
the intermediate section is located proximally relative to the distal end of the sheath,
when the connector is located between the first leg and the second leg, the intermediate section receives an outward force from the connector,
