Abstract

A clamp structure having a metal band body is mountable on a surface to be clamped. Small projections rising substantially vertically are formed on an inner lap portion of the metal band body. Receiving holes having an edge portion engageable with the projections are formed in an outer lap portion of the metal band body. A first tool receiving portion is formed on the outer lap portion of the body. A second tool receiving portion and a terminal holding portion are provided on an intermediate portion positioned in the longitudinal direction of the metal band body. The terminal holding portion has an opening for receiving the first end of the body when the projections are inserted into the receiving holes to fasten the metal band body. A temporary attaching means having a passage provided between the terminal holding portion and the projections temporarily attaches the metal band body by constraining the outer and inner portions to be engaged with each other when the metal band body is being fastened.
