A hyperextension orthosis includes a fastener casing mounted on a free end of the orthosis side-piece. The fastener casing releasably receives one end of a waist belt. The fastener casing has a spring arm with a catch on one end. When the waist belt is pushed into an insertion slot extending through the fastener casing, the catch automatically engages under a spring action one of several locking cutouts in the waist belt. The catch can be unlocked by manually pressing together two slides mounted to a frame member of the fastener casing for transverse displacement relative to the insertion slot. At an end opposite the catch, the spring arm has a stud, spring, or the like that engages a groove, bore, or the like in the side-piece in a positive fit. |
