Abstract: A cord clamp comprises an arm, a cord support member, an arm support member, a hinge portion between the arm and the arm support member, a fixing member to fasten the cord clamp on a base plate, and first and second hooks provided on the arm support member to position the arm. The arm can swing on the hinge portion so as to be secured selectively at a first position by means of the first hook and at a second position by means of the second hook, wherein the first position is perpendicular to the second position. The cord support member is provided with a recess to secure a cord therein, and beneath the recess is a slit where the cord can move in its axial direction.
