  • Pipe coupling
    Patent number: 4426106
    Abstract: A pipe coupling for connecting pipes end to end in fluid tight fashion. A sleeve having open ends receives the end portions of the pipes. The sleeve has a pair of ribs on its inside surface which snap into mating grooves on the pipe ends when the pipe ends are fully inserted. A clamping band is tightened on the sleeve to squeeze it against the pipes and to deform the ribs such that they completely fill the grooves. A series of striations on the inside surface of the sleeve also seal against the pipes.
