A pipe fitting coupling has a generally ring-shaped body with two pairs of diametrically opposed radially outwardly projecting lugs spaced 90°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.

A pipe coupling system for fluid lines comprising: a first pipe fitting having a central body defining a fluid flow path with first and second axially opposite ends having openings and a third laterally directed opening between said end openings and in communication with the fluid flow path; a first pair of radially outwardly projecting diametrically opposed lugs about said third opening, said openings and said lugs being aligned in a plane passing through the first, second and third openings; a second pipe fitting having a central body defining a flow path between end openings thereof and having a bend between said end openings; a second pair of radially outwardly projecting, diametrically opposed, circumferentially spaced lugs about one of the opposite end openings of said second pipe fitting, said opposite end openings, said flow path and said lugs of said second pipe fitting lying in a plane; a generally ring-shaped coupling for joining said first and second pipe fittings to one another with said third opening of said first pipe fitting and said one of said opposite end openings in fluid communication with one another, said first and second pipe fittings being oriented with the planes thereof lying non-parallel to one another and with said first and second pairs of lugs being misaligned with one another; said coupling having a third pair of lugs spaced from one another for alignment with the first pair of lugs about said third opening and a fourth pair of lugs spaced from one another for alignment with the second pair of lugs about said one end opening; and first retaining devices for securing the aligned first and third pair of lugs of said coupling to one another and second retaining devices for securing the aligned second and fourth pairs of lugs of said coupling to one another, thereby securing said first and second pipe fittings to one another.
