A cam and groove coupling joint has a male coupling and a female coupling that includes two pairs of lugs on the body and further includes pins supported by each pair of lugs. A pair of cam arms are pivotally mounted to the pins between the lugs. The cam arms are movable between an open position in which the male coupling is free to move relative to the female coupling and a closed position in which a cam of each cam arm engages the groove to lock the male coupling inside the female coupling. A rotatable wire clip secures the cam arms in the closed position, the wire clip being rotatably connected to each lug between a secured position in which the wire clip secures the cam arm to prevent opening of the cam arm and an unsecured position in which the cam arm is free to be opened.
