<p>PURPOSE: To improve fastening of a fastened object and make it correspond to aging or creep deformation of the fastened object after fastening, by forming a spring part which acts in the contracting direction in the case of clamping in a band plate. CONSTITUTION: In order to fasten a hose by a fastening band 1, the first operating piece 13 is superposed on an overlapping part 4 on the side of a second operating piece 6, to place the first/second operating pieces 13, 6 adjacent, to form a ring of the fastening band 1 into a small diameter, and a lock pawl 5, in a position improving a fastening condition is inserted, into a lock hole 14. At fastening time, a spring part 15 is placed in a pull energized condition and a periphery of the hose is fastened and kept by a ring-shaped part of a small diameter of the fastening band 1. After fastening, in the case decreasing thickness of the hose, the ring-shaped part is automatically diametrically contracted by spring action in the contracting direction of the spring part. According, the band corresponds to decrease of the thickness after fastening, so that fastening force in a connection part can be maintained.</p> |
