Abstract
A threaded coupling wherein external threads of the male body of the male coupling half are in mating engagement with internal threads of the female sleeve of the female coupling half. The female sleeve includes an interior hook and the male body includes a locking lever receptacle recessed therein as well as first and second slots for receiving first and second pins of the locking lever. The locking lever pivotally resides in the receptacle and interlocks with the hook of the female sleeve uniting the male and female. A tensioning O-ring secures the locking lever to the male body. A locking sleeve extends circumferentially about the male body and prohibits the release of the hook of the female sleeve from a recess in the locking lever unless a window is aligned with the locking lever. A process for locking the threaded coupling is also disclosed.
