Abstract:
A no-hub connector has a tubular gasket enclosed by a tubular shield and includes two end clamps and two intermediate clamps to tighten the connector around the ends of two pipe sections joined by the connector. Axially extending straps are fastened to each ring clamp, and fastened to the shield at the location of each ring clamp encircling the shield. An inward facing shield surface has optional gripping projections and the shield may optionally extend axially past the intermediate clamps to the end clamps. The inward facing surface of the end clamps may have optional gripping projections if the shield does not extend axially to the end clamps.
