ABSTRACT:
A new open end pipe or tube clamp assembly having an exceptionally high strength-to-size ratio which utilizes a U-bolt and a novel saddle member. The saddle is formed by a progressive die of a single piece with no welding and has a top web surface which is severely formed to define a pair of spaced rounded ridges and a depressed central portion achieving high strength and the ridges also serve as nut seats and reduce galling. The side walls of the saddle are centrally depressed to provide narrow contact with the tubing. When the clamp is tightened about a pipe joint high tension stresses force the side members toward each other.
