<p>PROBLEM TO BE SOLVED: To manufacture a spring band cramp at a low cost, and diminish a risk caused by the spring band cramp's unintentional closing though opened beforehand. SOLUTION: A spring band cramp is equipped with two ends 12, and so on at which projected fastening jaws 13, 14 are arranged so as to be opened. When the spring band cramp is opened, a tongue 17 pressurized on the outside of the end receives a closing spring force component having supporting means 18 so as to support a supporting surface 19 having an angle A against the radius R of the cramp at the free end of the fastening jaw 14 at the other end 12. The supporting means 18 is formed by the radially inner side edge of the free end surface of the tongue 17, and the radius R regulated at the angle A is brought in contact with the radially inner side edge 21 of the supporting surface 19.</p> |
