Abstract
A device for locking a piping with a small diameter at a bend formed into almost S- or C-shape at a proper portion longitudinal of the piping, which is clasped by one side wall end portion of a strap clamp member curved segmentally in section. The clasping portion is constituted of a curved wall and a holdfast wall or formed only of the holdfast wall. For locking, the piping is bent or curved at a proper longitudinal portion, and then clasped thereat by the clamp member formed into a shape coincident with the bend. The piping is locked otherwise from having a straight portion clasped beforehand by the clamp member, and then the clasping portion subjected to a press working on a grooved die, thereby forming a uniform bend according to the grooves.
