PURPOSE: A middle hinge structure of a clamp is provided to improve workability as a middle hinge is easily joined to an accurate spot of a pressing piece. CONSTITUTION: A clamp (1) includes a fixture (10) having a plurality of fixing holes (11); a pressing piece (20) pivot holes (21) on both sides to be hinge-joined to the fixture; a middle hinge (30) with joining holes (31) on both sides to be pivot-joined to the pressing piece; a hanger loop (40) with a screw thread (41) on the outer periphery of both end portions to be hung on or separated from a hanging groove of a fixed member. The hanger loop is joined to the middle hinge to be detachable. A position adjusting groove (70) is formed on one of the pivot holes formed on both sides of the pressing piece. A position adjusting protrusion unit (80) penetrating through the position adjusting groove is formed on the central portion (32) of the middle hinge so that the middle hinge is inserted into the other pivot hole.
