1. A shortening clutch for connecting one chain and another chain, the shortening clutch comprising:
a main body coupled to the one chain and including a pocket for accommodating a first chain link of the another chain; and
a lock lever which is pivotably attached to the main body through a pivot point having an urging member, is capable of switching between a locked state and an unlocked state by pivoting, and in the locked state, restricts disengagement of the first chain link accommodated in the pocket, from the pocket, while in the unlocked state in which the lock lever resists an urging force of the urging member, allowing the first chain link to disengage from the pocket,
wherein the lock lever includes:
a locking piece which, in the locked state, projects from the pivot point to the pocket side, in which the locking piece projects toward a position where the locking piece restricts movement of a second chain link of the another chain in an escaping direction, and the second chain link is adjacently coupled, on a side opposite to the escaping direction of the first chain link, to the first chain link accommodated in the pocket;
a first operating piece extending from the pivot point toward a side where the one chain is coupled; and
a second operating piece extending from the pivot point toward a side opposite to the side where the one chain is coupled.
