Claim:
1. A cam lock fitting, comprising: a) a male and a female conduit, said male and female conduits for being connected to each other, said male conduit having an end thereon and an external peripheral groove adjacent said end, said female conduit having an end thereon and an internal seal disposed therein adjacent said end, wherein said end of said male conduit contacts said seal of said female conduit thereby preventing leakage when said male and female conduits are connected to each other, b) a first and a second pair of cam members, each pair having first and second cam members a pair of said cam members being disposed on opposite sides of said female conduit, each said can member having a cam portion wherein each said cam portion is adapted to pivot through an opening in a wall of said female conduit and into said external peripheral groove so as to removably join said male conduit to said female conduit, wherein said cam portion of each said first cam member is larger than said cam portion of each said second cam member, wherein each said cam member has a closed position when said male and female conduits are connected to each other and a open position when said male and female conduits are disconnected from each other; c) each said cam member having an operator usable lever arm for actuation thereof; d) wherein said cam portions of said second cam members are forked, said forks having a space thereinbetween, wherein said cam portions of said first cam members are pivotally disposed in a respective said space; and, e) said male conduit having a partially open position in which said male and female conduits are slightly separated from each other thereby allowing leakage between said male and female conduits when each said first cam member is in said open position and each said second cam member is in said closed position, wherein if said leakage is observed by an operator each said first cam member is pivoted back to said closed position to permit the male and female conduits to be reconnected to each other.
