ABSTRACT:
A locking cam-type coupling for rapidly coupling two pipe sections together. A spring-biased lock pin is provided for each cam lever arm that has a positive locking action when the cam lever arm is moved to the closed position. Each cam lever arm is grooved to allow the spring-biased lock pin to contact the cam lever arm and control its position. The lock pin has two different diameters, one for locking the fitting to the complementary part of the pipe coupling to couple the pipe sections together, and a second, open position so the pipe sections can be released and decoupled.
