A ligating apparatus includes a clip, a clip connecting member, a clip holding member, an operating wire, an inner sheath member, an outer sheath member and first and second movement restricting portions. The clip ligates a body tissue with arm portions. The clip connecting member connects to a clip base portion. The clip connecting member is inserted through the clip holding member. The operating wire connects to the clip connecting member. The inner sheath member encloses the operating wire to support the clip holding member. The outer sheath member covers an outer periphery of the inner sheath member and freely advances and retreats. The outer sheath member advances and/or retreats to change the degree of opening of the arm portions. The first movement restricting portion restricts the inward movement of the clip holding member. The second movement restricting portion restricts the outward movement of the clip holding member.
