The theme of the disclosure includes that the misconnection of the fluid coupling of those embodiments prevents or hinder fluid line. Attachment device include multiple male and female connectors that be connected to common wire. Coupling device is only property connection in all multiple male and female connectors by the coupling arrangement to match has been bonded. If not mating properly into the corresponding of connector, coupling can be leaked. The coupling device be allowed to uniquely by provide the arrangement of connector, the number of connector, the shape of connector or arrangement interference connector part that ensure it is any attempt will improperly to connect two fluid lines will lead to one or more connectors of Incomplete matching, it fails so as to cause liquid leakage and connects engagement, or otherwise make to attempt Joint failure.
