Claim:
1. A quick connect hydraulic coupling with a retention mechanism to prevent inadvertent disconnection, comprising: a female coupling with an external surface and an internal surface which defines a port; a male coupling having an external surface, an internal surface, a leading edge, a longitudinal axis, and a geometric profile adapted for insertion into said female coupling; and a stop mechanism disposed at least partially around the external surface of the male coupling and configured to prevent the male coupling from being inserted into said port of the female coupling beyond a predetermined position, the stop mechanism slidable relative to the longitudinal axis of the male coupling between a first position and a second position, the first position located between the leading edge of the male coupling and the second position, the stop mechanism biased towards the first position so that the stop mechanism resets to the first position upon removal of an insertion force; wherein when in the first position, the stop mechanism is incapable of sliding toward the second position without a repositioning of the stop mechanism; and wherein the external surface of the male coupling has an annular groove and the stop mechanism has an internal surface with a protrusion extending inwardly, wherein when the stop mechanism is in the first position, the protrusion is seated in the groove to substantially prevent axial movement of the stop mechanism relative to the longitudinal axis.
