a clip unit that has a first link;
a second link provided at a distal end of an operation wire inserted into a sheath;
a slider connected to the operation wire; and
a limiter configured to limit movement of the slider, the connecting method comprising:
restricting movement of the slider with the limiter with a first operation, the restricted movement of the slider being in a first direction;
releasing the restricted movement of the slider by the limiter with a second operation by operating a switch in a second direction that intersects the first direction;
first moving the second link with the first operation from an accommodation position where the second link is accommodated in the sheath to a protrusion position where the second link protrudes from the sheath;
fitting the second link to the first link at the protrusion position;
then moving the second link that is fitted to the first link with the first operation to the accommodation position; and
again restricting the movement of the slider with the second operation.
