a material attached to the first frame for fitting to the body part; and
a plurality of pivoting clamps mounted to the first frame, and forming constituent components of the first frame and not the second frame, and each having a clamping arm that is configured to pivot, relative to the outer, lateral edge of the first frame, to enable the clamping arm to engage with an outer, lateral edge of the upper flange of the second frame and with the outer, lateral edge of the first frame to clamp the first frame to the upper flange of the second frame when the first surface of the first frame is docked with the docking surface of the second frame, wherein the clamping arm comprises an upper clamping arm, a lower clamping arm, and a clamping space between the upper clamping arm and the lower clamping arm, and wherein the clamping arm is further configured such that, when engaged to clamp the outer, lateral edge of the first frame to the outer, lateral edge of the upper flange of the second frame, the upper clamping arm and the lower clamping arm do not extend inwards from the outer, lateral edge of the first frame beyond a boundary defined within a region between the outer, lateral edge and the inner, lateral edge of the first frame.
