a plurality of arms having sliding grooves respectively; and
an intermediate member inserted into the sliding grooves for connecting the plurality of arms;

a pressing tube configured to accommodate a proximal end portion of the clip;
a connection member configured to connect with an operation wire at a proximal end side and including an engaging portion to engage with the intermediate member; and
