Energy shackle

An energy shackle is a piece of Covenant technology used to physically restrain an individual. The Banished later used this technology to restrain prisoners, as well.

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. Energy shackles used by the Banished emitted orange-red rings of energy, but otherwise served the exact same function.

Usage history
In October 2552, a pair of energy shackles were used to restrain Thel 'Vadamee while he was branded with the Mark of Shame. Sali 'Nyon was bound by a set of energy shackles when he was captured by Jul 'Mdama's forces in July 2558. During the Battle for Zeta Halo, Spartan Hudson Griffin and Fernando Esparza were restrained inside Banished torture machines by energy shackles.
