Abstract: A system is shown for differentiating two or more cables of two or more respective appliances. The system comprises respective means in the form of tag devices for positioning on and labelling each cable, wherein each tag device is provided in a differentiated form from each other tag device. The tag devices can be pre-printed or supplied with suitable indicia for positioning thereon. Such a system for identification can allow a user to more readily identify the appliance to which the cable is connected, or in the case of use of the system for labelling and identifying containers, to identify a container and its contents. This can be useful in situations where a plurality of cables, or containers, are located in close proximity to one another.
