A heat shrinking tube is an excellent tool for connecting two wires, each with a different thickness, or to keep various thin wires together. You can cut a long piece of heat-shrink tube with a suitable diameter to the preferred size. Place the tube around the wires and let it shrink by means of heating with a hot hair dryer, soldering iron or lighter (without touching the heat-shrink tube).
