Abstract
A coupling for no-hub pipe segments has a shield covering an elastomeric gasket. The shield has a plurality on corrugations oriented transverse to the pipe axis and arranged in discrete areas. These corrugations are separated by corrugations oriented parallel to the pipe axis arranged in discrete areas. Clamping bands securely clamp the shield and gasket to the pipe segments. The pattern of corrugations permits the shield to assume a shouldered shape when the clamping bands are tightened and the coupling is installed on pipes of slightly varying diameter. The gasket is provided with a pattern of thick sealing sectors and adjacent groove sectors laterally spaced relative to thick sealing sectors. This pattern permits the clamping bands and shield to form a restriction impeding the movement of the shield relative to the gasket when the clamping bands are tightened.
