Abstract: Disclosed are methods and apparatus that allow hand forces to easily cinch up and tighten a slotted band of a hose clamp to a position where a worm gear screw may then be used to firmly tightening the hose clamp around a hose or pipe. A cinching operation may be accomplished using a pawl apparatus provided at one end of a hose clamp having a centrally located downwardly facing tooth provided between a pair of oppositely positioned side walls which act as guides for receiving a slotted band of a hose clamp. A tightening operation may then be accomplished by turning the screw of a worm gear at the other end of the hose clamp. The hose clamp may be removed by releasing the pawl assembly or unscrewing the worm and gear screw.

Abstract: The apparatus is a pawl clamping rachet device used with pipe or hose clamps when working in a tight space limiting access to advancing a slotted band needed for tightening the hose clamp. The apparatus having upstanding planar guide walls which guide a slotted band as the band is advanced through a gap with the band restrained in moving backwards by a pawl tooth having a spring function.
