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