ABSTRACT:
A mounting ring of synthetic material for fitting two pipe sections in place relative to each other, has a radial flange (1) and an axial neck (2). Tongues (3, 4, 5, 6) of differing lengths extend radially inwardly and radially outwardly from the neck. These tongues are preferably formed as part of the ring, for example, when molding the ring of synthetic material. The longer radially outer tongues bend over, snap into a groove, and center the ring in a pipe socket. The shorter radially outer tongues support the ring in the socket. When a pipe end is inserted into the socket through the ring the longer radially inner tongues bend and center the pipe in the socket while the shorter radially inner tongues support the pipe end. Thus, the inner surfaces of the pipe sections remain in alignment with each other because the shorter tongues act like spokes against forces acting crosswise on the pipe sections relative to their length.
