A coupling device for an orthopedic brace includes an anchoring member for securing to a frame and protruding therefrom, and a subshell arranged to connect to the frame by the anchoring member. The subshell has a locking element for selectively positioning the subshell on the frame at a plurality of locations. The subshell may include an end portion or contoured edge extending beyond a portion of the frame so as to flex relative to the frame.
