Bashir is released from his restraints before being placed in a holding cell
Handcuffs, known colloquially as irons or cuffs, are a type of restraint that limit an individual's wrist movement.
In 2151, a team of Ferengi successfully subdued the crew of Enterprise NX-01 and boarded the ship with the intent on stealing anything of value. After they were unable to locate a vault, they revived Captain Jonathan Archer to question him, but not before handcuffing him to a bulkhead to prevent his escape. (ENT: "Acquisition")
Enolian handcuffs had built-in pain receptors which could be activated by remote. In 2152, Captain Archer was captured by the Enolians and placed in handcuffs of this kind. (ENT: "Canamar")
In 2373, Captain Benjamin Sisko forced Maquis leader Michael Eddington to accompany him a Template:ShipClass runabout to stop several missiles that were supposedly heading for Cardassian space. During their time on the runabout, the Captain ensured Eddington remained in his handcuffs though later took them off him during a firefight with Jem'Hadar forces. (DS9: "Blaze of Glory")
In 2374, Doctor Julian Bashir was handcuffed and paraded down the Promenade of Deep Space 9 to the security office, during Luther Sloan's holographic recreation of the station. The holographic representation of Captain Sisko protested, claiming a Starfleet officer shouldn't be dragged across the Promenade in irons. (DS9: "Inquisition")
