SINGLE AND MULTIPLE SECTION PIPE REPAIR CLAMPS ABSTRACT OF THE DISCLOSURE A low profile clamp for use in encircling a pipe such as a main or the like, the clamp being either a repair clamp or a service clamp with a side outlet. The pipe clamp comprises a flexible band, usually of sheet metal with a gasket material on the interior and having at least a pair of opposed looped ends which receive cylindrical trunnion loading bars. At least one bolt extending through the loading is arranged to move the trunnion loading bars toward each other to cause the looped ends of the band to draw the flexible band tightly around the pipe. The relationship of the trunnion loading bars to the bolt extending therethrough is such as to give the clamp a use for a wide range of varying outside diameters of a particular size of pipe. Means are provided for retaining the bolt in one of the loading bars prior to assembly of the clamp on a pipe, and also means are provided for frictionally holding the trunnion loading bars in a predetermined position in the looped ends of the flexible band prior to assembly of the clamp on a pipe but yet let the trunnion loading bars rotate relative the looped ends during assembly. The loading bars are capable of removal from the looped ends if it is desired to replace the same.
