Abstract: A quick release band clamp having a mounting bracket attached to one end of a flexible band. The mounting bracket has a pair of side support members straddling the flexible band. A pivoting bracket is pivotably supported between the pair of side support members by a pair of transverse trunnions and is pivotable between a closed position and an opened position. A worm screw is rotatably supported by the pivoting bracket at a location intermediate the trunnions and the band clamp. The free end of the band clamp is receivable between the mounting bracket and the pivoting bracket. The helical threads of the worm screw engage the teeth provided on the free end of the flexible band when the pivoting bracket is rotated to the closed position. In this position, the flexible band may be advanced through the mounting bracket by the rotation of the worm screw to tighten the flexible band about an object.
