Abstract

Abstract A tubular-shaped body is split longitudinally into two sections for positioning on opposite sides of a pipeline. A hinge is located on each side of the body for connecting the two sections along each side of the split for pivotal movement around axes that are parallel and that are parallel to the longitudinal axis of the pipeline. One of the hinges has a removable hinge pin to allow the two sections to be moved apart for placement around the pipeline. The other hinge has a hinge pin with an eccentric portion that will cause the two sections to clamp the pipeline between them when the pin is rotated.
