A fluid coupling including coded and non-coded embodiments and a method for their use. The coded embodiment allows connection of such lines while preventing the inadvertent connection of mismatched lines in a system where there are matched and mismatched delivery and supply lines. Both embodiments of the coupling include axially movable first and second coupling members and a radially operating latch. The coupling members are releasably slideably, axially interfitted with their fluid passageways in communication, and the latch moves radially of the passageways to secure the couplings when they are interfitted. In the coded embodiment, key coding elements on the coded coupling members are movable into matched interengagement when the supply and delivery lines are matched but are precluded from moving into matched interengagement when the lines are mismatched. If a match exists, the coding elements interfit by limited rotation of one of the key coding elements but without rotation of the coupling members and without any threading action of the parts. A mechanism latches the couplings together when the key coding elements match and allow the coupling members to interfit but does not latch when the key coding elements do not match and thus do not allow an interfit. In both embodiments, the coupling members are uncoupled solely by axial separation of the parts, again with out threading, and in the case of the first embodiment, without even any rotation of the parts. In both cases, therefore, neither the coupling members, the coding elements, nor the latch involves threaded connections, whether for connection or disconnection or for latching or unlatching.
