ABSTRACT OF THE DISCLOSURE A pipe joint coupling for joining cast iron hubless drain and vent pipes. The joint is encircled by an annular elastic gasket fitting over each end of the adjacent pipe sections. The elastic gasket is surrounded by a shield with a diamond pattern of projections and depressions. The shield is tightened by bands to compress the gasket against the pipes and to secure the adjacent ends of the pipes together. A tight seal is formed between the gasket and the pipe ends which is maintained under high pressure fluid passing through the pipes. The gasket is prevented from extruding from the shield by the gripping of the projections of the diamond pattern of the shield on the gasket. An improved seal between the pipes being joined is formed with increased resistant to the displacement of the gasket.
