SUMMARY OF THE INVENTION In the conventional hose band described above, the band member and the tightening member are connected by spot welding. However, in spot welding, it is difficult to guarantee 100% because it is impossible to inspect whether the weld is good or bad without destroying it, and it has the disadvantage of low reliability. In particular, stainless steel is difficult to weld, which further reduces reliability. In addition, in spot welding, rust is likely to occur in the welded part, and there is a risk of a decrease in strength. Furthermore, since heat is applied during welding, there is a risk that the hose or the like, which is the member to be tightened, will be damaged, resulting in a decrease in strength. In view of these points, it is an object of the present invention to provide a hose band that solves the above-mentioned drawbacks.
