An inverted-U shaped support frame (1) is secured to the ground at its two free ends, and supports a panel (3) between its two upright portions (10). The panel is attached to the frame by transverse screws passing through its lateral edges and into the frame members, via intermediate spacers (31). The panel may be formed by a pair of profiled metal lateral members, supporting a sheet of less rigid material between them. The front surface of the panel may support a pair of slidable glazing sheets (40,41) with a locking mechanism (42) for selective fastening. Combinations of more than one panel may also be assembled within a wider support frame.
