A cam and groove coupling joint has a male coupling having a substantially tubular body that includes a pair of grooves in the body and a female coupling having a substantially tubular body that includes two pairs of lugs on the body and further includes pins that are 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 wire clip secures the cam arms in the closed position, the wire clip being movable 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, wherein the wire clip has a first segment of wire extending through holes in the lugs such that the wire clip is able to slide orthogonally with respect to the cam arm while being permanently mounted to the female coupling and wherein the wire clip has a second segment substantially parallel to the first segment that is extendable over the cam arm to secure the cam arm. |
