ABSTRACT:
A hose clamp which has an expanding portion of increased width at predetermined parts of a clamping portion is so formed as to produce a constant stress caused by the bending moment of forces and the axial force acting on the position where the maximum stress is applied to the clamping portion. The hose clamp has a first gripping end portion and a pair of second gripping end portions to expand the diameter of the clamping portion. Plastic deformation is prevented at the time of expanding the diameter of the clamping portion of the hose clamp.
