Abstract: Pipe joints, particularly a restraining joint for use in bell and plain pipe end assemblies. The joint includes a gland having a conical axial aperture which encircles the plain end of the pipe; a split ring also encircling the plain end of the pipe is set in juxtaposition with the gland and this ring includes a peripheral flange which seats in the gland. The split ring has a conical exterior complementally engaging the conical axial aperture in the gland and a plurality of pipe gripping teeth defined in its inner surface. A compressible gasket is interposed between the split ring and the pipe bell. The restraining joint is particularly effective in joining plastic pipe and bell assemblies.
