Abstract: Fluid couplings prevent or discourage misconnection of fluid lines. In embodiments, a coupling device includes multiple male and female connectors that are joined to a common line. The coupling device is mated to a matching coupling device only when all the multiple male and female connectors are properly joined. If any of the connectors is not properly mated to a corresponding one, the coupling will leak, since the connectors on each side are joined to a furcating channel. In embodiments, the coupling devices are made unique by providing an arrangement of the connectors, number of connectors, shape of connectors or arrangement of interfering connector parts that ensure that any attempt to improperly couple two fluid lines will result in the incomplete mating and thereby cause leakage of the fluid, failure of the coupling to engage, or otherwise cause the attempt to connect to fail.
