An identification system includes a clamshell device that grasps a wire, and a clip that secures the clamshell device in a locked and closed position. The clamshell and/or clip are preferably color-coded to differentiate one wire from another, hereby allowing a technician to easily discern which wire is plugged into which port, and which wire is connected to which patient. The invention is particularly well suited for incorporation with healthcare devices and machines which have long lead wires that reach from the patient to the machine, such as electrical stimulation machines.
