Binding links are symbols that can keep a demons, or any other possessing entity trapped inside its meatsuit i.e. the human it is possessing, and in the case of demons they can neither escape voluntarily or be exorcised. Binding sigils can be etched on to various types of restraints, where they work in the same way as having been carved into the flesh.
Certain binding sigils, like the ones etched on the handcuffs Sam and Dean discovered in the Men of Letters Bunker, also appear to weaken the powers of the prisoners they place into them. Known colloquially as "angel cuffs" by the Winchesters, in addition to binding and weakening demons, the handcuffs also work on reapers and angels, but are not strong enough to hold an archangel.
Binding links may also be related to the "binding magic" used on curse boxes to keep the evil inside.
