PURPOSE: A belt-type clamp is provided to tightly fasten a duct by preventing a fastening bolt from being slid by a temporary stopping sill and a final stopping sill. CONSTITUTION: A belt-type clamp comprises a stopper(36) and a fastening bolt(40). The stopper composes a horizontal stopper(36a) and a vertical stopper(36b). The horizontal stopper surrounds the upper part of a side plate(22), and the vertical stopper surrounds an exterior surface of the side plate. A temporary stopping sill(22a) is protruded on the top of the side plate and temporally restricts the horizontal stopper entering to an inclined slot hole so that the vertical stopper is not pushed toward the inclined slot hole when the fastening bolt is fastened. The horizontal stopper instantaneously crosses over the temporary stopping sill, and the vertical stopper is pushed toward the inclined slot hole simultaneously when the fastening bolt is fastened more so that the horizontal stopper is finally stopped. |
