Abstract

A clamp band has an inner end and an outer end. A first tool engaging portion to be engaged with one of paired clamping force application portions of a clamping tool, a first clamp portion and a projection adjacent to the first clamp portion are formed in sequence as viewed from a tip edge of the inner end. A second clamp portion to be engaged with the first clamp portion is formed near a tip edge of the outer end, and a second tool engaging portion to be engaged with the other clamping force application portion of the clamping tool is formed on the outer end at a position further from the tip edge. A distance between the first clamp portion and the projection and a distance between the second clamp portion and the tip edge of the second end are selected such that the tip edge of the second end is juxtaposed to an end edge of the projection when the first clamp portion is engaged with the second clamp portion.
