ABSTRACT:
A pipe fitting coupling has a generally ring-shaped body with two pairs of diametrically opposed radially outwardly projecting lugs spaced 90.degree. one from the other. The coupling is interposed between the bells of pipe fittings to be joined, with each bell having only a pair of misaligned diametrically opposed lugs. The lugs on the coupling align with the misaligned lugs of the pipe fittings and restraints are disposed about the aligned lugs to secure the pipe fittings to one another.
