Abstract: The invention contemplates a hose clamp comprising an elongate channel frame with opposed upstanding side walls from which a compression drum is pivotally suspended. The drum has two arcuate hose-compression surfaces on offset axes. For the compression surface of larger radius, the pivot axis is substantially diametrically opposed to the circumferentially central region of said larger-radius surface; and for the compression surface of smaller radius, the pivot axis is close to the axis of said smaller-radius surface. An integral handle extends in a direction generally transverse to the plane of compression-surface axes. The pivot support provided by the channel walls is such that, in one direction of lowering the handle toward the channel bottom, an inserted flexible hose may be clamped shut, and for the other direction of lowering the handle toward the channel bottom, a fine degree of metering control is achieved for flow in the hose.
