ABSTRACT:
A band clamp comprising a sleeve and a tightening mechanism that includes at least one fastener, such as a nut and bolt, as well as a reaction member which is constructed of a single piece of sheet metal. The reaction member is disposed between the end flanges of the clamp sleeve and can be shaped such that it is forcibly pressed into engagement with the underlying pipe when the clamp is tightened. The reaction member can be a separate component retained between the flanges by engagement of end portions of the reaction member with retainer ears on the flanges. Alternatively, the end flanges and reaction member can all be unitary portions of the clamp sleeve such that the complete band clamp, except for the bolt and nut, is comprised of a unitary piece of sheet metal.
