A connector that can detachably and firmly connect two members to be connected to each other. Two facing lever members (2A, 2B) are constructed so as to be rockable about a support point member (3). Ascrew hole (2Ac) is formed in the lever member (2A), and an insertion hole (2bd) through which a screw (5) is inserted is formed in the lever member (2B). When the screw (5) is threaded into the screw hole (2Ac), both the lever members (2A, 2B) come closer together. By this, engagement sections (2Ab', 2Bb') of the lever members (2A, 2B) spring upward, moving relative to the support point member (3) forming a support point section (F). A fixer body (1) is fixed by a screw (4), which penetrates through the support point member (3), to one of two members that are to be connected to each other, and the engagement sections (2Ab', 2Bb') are engaged with the other of the two members. As a result, rocking motion of the engagement sections (2Ab', 2Bb') causes force to act on both the members thatare to be connected, bringing them closer to each other, and this fixes the members together. The force is released when the screw (5) is threaded back, so that both the members can be easily releasedfrom the fixation.
