Artron leash

An artron leash was Gallifreyan technology. It was used to keep the person on the receiving end close to the other because if they were a certain distance apart, the person on the receiving end would be given an electric shock.
The War Ollistra attached the War Doctor with one, linking it to herself.  (AUDIO: A Thing of Guile)
