[Problems to be Solved by the Invention] However, in the above-described conventional art, since the deposition is performed on the straight pipe peripheral surface portion in the length direction on the pipe (P 1 ) side, or the welding peripheral surface is brazed, In the former case, due to the vibration of the vehicle body, machine, or equipment for a long time in the installed state, in the former case, the pipe (P 1 ) is displaced in the length direction and the circumferential direction, or scratches are generated. If it is tightened, it may cause cracks or damage. In the latter case, the corrosion-resistant coating is applied to the entire product after heating and brazing, so that the plating process in a complicated bent shape causes a great deal of work trouble. There is a problem that workability is hindered and it is difficult to form a plating film having a desired high corrosion resistance.

[Operation] Since the present invention is configured as described above, after the clamp body (1) is attached to the proper position of the pipe (P) in the straight pipe state by wrapping the gripping wall (3), The clamp body and the pipe are integrally bent by a collective pressing molding process using a split mold to form a relatively loose bent portion (P '), and thereby the bent portion has a cross-sectioned gripping wall (4). By being attached in a wrapped manner by the pipe, the pipe is displaced relative to the clamp body in both the longitudinal direction (that is, the pipe is displaced by pulling or pressing in the longitudinal direction) and the circumferential position. As a result, it is possible to securely engage and fix without causing a displacement (a displacement due to twisting in the circumferential direction).

[Effects of the Invention] As described above, the fastening and fixing pipe by the clamp body according to the present invention and the method for fixing the same are clamped by wrapping the gripping wall (3) at an appropriate position of the pipe (P) in a straight loose state ( After 1) is attached, the clamp body and the pipe are integrally bent by a collective press molding process using a pair of split molds to form a relatively loose bent portion (P '), and thereby the bent portion is cross-sectioned. Even if it is in a vibrating state for long-term disposition, the displacement in both the length direction of the pipe side with respect to the clamp body can be achieved by the covering engagement of the gripping wall (4) in the shape of a circle. And the positional deviation in the circumferential direction is prevented by the eccentric engagement between the inner peripheral surface of the gripping wall and the outer peripheral wall of the pipe at the bent portion, and therefore, the scratches, cracks, or damages generated on the pipe side at the engaging portion. It can be fixed and locked securely by preventing Furthermore, it is possible to use pipes and clamps that have been subjected to coating treatment by plating, etc., and it is possible to significantly improve workability by eliminating the need for plating after fastening and fixing. It is a pipe and its fixing method.
