Energy shackle

An energy shackle is a piece of Covenant technology used to physically restrain an individual.

Overview
When activated, the energy shackle emits a blue ring of energy around one of the limbs of an individual, and levitates in a fixed position, making it extremely difficult to move. The shackle also has the ability to electrocute the restrained individual.

Trivia
In 2552, a pair of energy shackles were used to restrain Thel 'Vadamee while he was branded with the Mark of Shame.
