Abstract
An assembly for closing a side opening in a pipe and including a fitting attached to the pipe and having a tubular portion aligned with the opening and a completion plug inserted into the tubular portion to seal the opening from the exterior of the pipe. The completion plug is provided with circumferentially spaced lugs lying in a plane normal to the axis of the plug, the lugs being arranged to fit into a groove in the tubular portion of the fitting, there being spaced arcuate cutouts in the tubular portion whereby the arrangement is a bayonet-type of fastening. Stop means are provided to limit rotation of the plug in a closing direction and further stop means are provided for preventing inadvertent removal of the plug from the fitting. A third stop means is provided for stopping the plug when being rotated to a position for removal, the third stop means aligning the lugs of the plug with the cutouts in the fitting so that the plug can be retracted from the fitting.
