A removable two-ring clamp has a first segmented ring assembly and a second segmented ring assembly that pivot relative to one another and can be individually loosened and tightened. The first ring assembly is received on and secured around an end portion of a first tubular section and the second ring assembly is received on and secured around an end portion of a second tubular section. The ring assemblies, when loosened, allow relative pivotal movement therebetween and allow the tubular sections to be rotated about their axes relative to one another to accommodate positioning the axes of the sections in any combination of planes, and when tightened, firmly hold the two tubular sections concentrically end-to-end in the proper position while a small tack weld or bonding agent is placed at their joined ends.
