In a holder having a holder base and holding arms and used for holding a hose clamp in position, the holder base is so constructed as to be capable of being positioned on the outer periphery of an annular hose clamp and a pair of holding arms protrude from each of a pair of opposite lateral edges of the holder base. Each pair of holding arms are so shaped as to define a pair of opposed arcs extending along a circumference A having a diameter somewhat smaller than the outside diameter of a hose. Each holding arm has a sharp projection Bformed on its inner peripheral surface at its distal end and directed substantially toward the center of the circumference A, or more inwardly than it. The clamp holder facilitates the preliminary holding of a hose clamp in position on a hose without damaging the hose, and without slipping off the hose or being displaced easily.

Clamp holder

A hose clamping structureincludes: a metal pipehaving an inserting end portionstraightly extending in an axial direction at one end and having a ring-shaped projecting portionat a leading end of the inserting end portion; a rubber hoseinsertedly fitted to the entire outer surface of the inserting end portion by press-fitting and secured thereto in an unbonded manner; and a tubular sleeve membermounted to the outer surface of the rubber hose and extending over the substantially full length of the inserting end portion, and tightened from outside so as to clamp the rubber hose. The sleeve member includes a second tightening portionand a first tightening portionapart from each other in an axial direction. The first tightening portion includes a tubular portionsubstantially parallel with the axial direction at the side of the second tightening portion, and a tapered portiontapered and widened into a conical shape from the tubular portion toward the leading end of the inserting end portion.
