JOINT SLEEVE FOR PIPE Abstract of the Disclosure A joint sleeve is set forth for sealing the ends of adjacent pipe sections. Each pipe section end has a compressible sealing gasket encircling it proximate its end and a shoulder remote its end. The joint sleeve consists of a body able to encircle the pipe section ends and to compress the sealing gaskets so that an adequate seal is provided when the sleeve is disposed about adjacent pipe section ends. To resist the force imposed upon the sleeve by the rolled gasket which tends to urge the sleeve from the pipe end, the joint sleeve has an inner surface with a flared portion. When the sleeve is positioned on one pipe section end for storage and transport, the compressed gasket by virtue of the flared portion produces an axial force urging the joint sleeve body in a direction opposite the force imposed by the rolled gasket and against the shoulder to hold the sleeve on the one pipe section end. To assemble the pipe sections, the end of the other pipe section is inserted into the sleeve which also results in a force urging the sleeve against the shoulder. Due to the weight of the pipe sections, the reaction forces from the gaskets are ineffective to displace the pipe sections.
