<p>A connecting structure interconnects two sections (1 and 2) of a wall. Respective enlargements (3 and 4) define between them a wedge portion (5) of a dovetail joint. A locking rib (7) is slid over the wedge portion (5) so as to hold the two parts (3 and 4) together. This locking rib fits closely against the adjacent wall surfaces of the parts (3 and 4) of the wall sections (1 and 2) and in turn helps to define a smooth wall surface (8) which is contiguous with the walls (1 and 2), the connecting structure effectively being situated within a recessed portion of the inner wall.</p> |
