ABSTRACT:
A coupling assembly is provided that generally includes a female coupling selectively interconnected to a male coupling to provide sealing engagement. In one embodiment, the female coupling and the male coupling are secured together by a mechanical locking mechanism that is disengaged with a release mechanism. To prevent inadvertent disengagement, a secondary locking device or spacer is provided which substantially prevents the release mechanism from disengaging the locking mechanism.
