A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

A latch coupling includes male and female connector assemblies releasably secured together. The male connector assembly includes two parallel male connectors and first latches. The female connector assembly includes two parallel female connectors and second latches. A sleeve is releasably connected to an end of the female connector. Force is exerted on the second latches to hook the first latches so as to connect the female and male connector assemblies together. The parallel female connectors can be disconnected from the parallel male connectors or connected together at the same time. After the female connectors have disengaged from the male connectors, leakproof arrangements in the female connector assembly act to prevent water in the female connector assembly from leaking.
