What are the small metal bars called that enclose a wrist in handcuffs?

The small metal bars that enclose a wrist in handcuffs are commonly referred to as links. These are the components that connect the two halves of the handcuff and allow for adjustment to fit different wrist sizes securely. Links ensure that once the handcuffs are applied, they cannot be easily manipulated or removed.

Each link is designed to provide a degree of flexibility while maintaining a strong, secure hold, making them an essential part of the handcuff's overall function. Understanding the terminology related to handcuffs is crucial in a law enforcement context, as proper communication about equipment can enhance safety and efficiency during encounters.
