Plastic handcuffs, also known as flexible restraints or zip cuffs, are lightweight, disposable restraints made from durable plastic. They are often used by law enforcement and security personnel for temporarily securing individuals. Unlike traditional metal handcuffs, plastic handcuffs can be quickly applied and are designed for single use. These restraints typically consist of a long strip of plastic with a locking mechanism at one end. Once tightened around a person's wrists, they cannot be easily removed without cutting them off. Plastic handcuffs are particularly useful in situations where multiple arrests are made or when speed is essential.
