Abstract: A biased cuff assembly comfortably but securely cuffs extremities of a person. The assembly includes a cuff having a first arcuate section hingedly coupled to a second arcuate section configured to form a closed loop to secure the cuff to an extremity of a person. A sheath is pivotally coupled to the first arcuate section of the cuff. The first arcuate section of the cuff is positioned in a slot in the sheath. The sheath has an arcuate edge extending into an opening of the loop when the sheath is in a retracted position wherein the arcuate edge of the sheath is configured to contact the extremity extending through the loop. A biasing member is coupled to the first arcuate section of the cuff and positioned to bias the sheath to pivot outwardly away from the opening of the loop.
