ABSTRACT:
A pair of handcuffs formed of light weight plastic material, so that the handcuffs cannot be used by a prisoner as a striking weapon against a guard or police officer. A single flexible plastic cord is formed into two loop sections adapted to encircle the prisoner's wrists. Sections of the cord extend through a clamp device that can be manually operated to expand or contract the loop sections, as necessary to remove or install the handcuffs on the prisoner.
