ABSTRACT:
A quick-release mechanism for an orthodontic headgear assembly, which has a bracket integrally formed with a traction force device and a connecting structure attached to ends of a neckstrap or headstrap. The bracket has two opposite horizontal parallel arms that extend rearwardly and a vertical rod integrally attached between the two opposite parallel arms. The connecting structure is snapped onto the vertical rod for retaining the traction force device and the neckstrap in position. The quick-release mechanism is disconnected by vertically pulling the connecting structure and the bracket apart from each other at a predetermined force, thereby releasing the connecting structure from the bracket.
