Unplug the adaptor. Use your wire cutters to strip between a half inch and an inch off of the sheath that covers the wires. Be careful to cut only the sheath, and not the actual wires.

Wrap electrical tape around the wires to cover the gap in the sheath. Make sure it is electrical tape as it is designed for use with electricity.
