LUG-LESS OR STEPLESS CLAMP STRUCTURE

摘要

PURPOSE: To provide a clamp structure capable of securing the perfect liquid tightness of an object to be fastened and capable of being manufactured at a low cost while having the remarkably simple structure. CONSTITUTION: A clamp belt 11 of a continuous clamp structure is provided with a tongue-like extension part 20 at an end thereof, and provided with long hole-like opening at the other end thereof. Hooks 23 extended outside on the tongue-like extension part 20 are engaged with a folding end block 35 of the other end. Length of this folding end block is set so that a small part of the oblong hole-like opening exists therein. Depth (d) of the small part of the oblong hole-like opening is formed smaller than twice of the thickness of the clamp band and a little larger than the thickness of the clamp band.
