Next, the pipe is pressed from above the open portion of the groove and the upper portion of the pipe is deformed so that it follows the plane of the open portion of the groove, and moreover both side portions of the pipe are deformed so that they follow along the inner surfaces of both side portions of the groove. By this second process, both side portions of the pipe are engaged with the projections or concave portions.
