Abstract
Replacement fittings for substantially rigid pipes. Each fitting preferably includes a main body with telescoping, sleeve members mounted on it. The sleeve members can be individually slid along the main body but cannot be removed from it. In this manner, the preferred fittings of the present invention can be handled as a single unit and all of the linked pieces will stay together and cannot be inadvertently left behind. They also cannot be accidentally lost or dropped on the way to the job site or during the repair operation. The various pieces of the fittings employ tapering surfaces that not only ensure the pieces will stay together while the fittings are being manipulated into position but also aid in creating the strongest bonds and seals with the pipes.
