A self-supporting wall is formed by assembling tubular elements with a longitudinal portion having a concave arc-shaped cross-section by means of joints being link plates of two different types. One type, with a central raised portion and two bored pins, and the other, with a lower spacer member and two dead-end hole pins, alternately link together the elements placed side by side, through plug members adapted to fit into a central passage of each element and to be coupled to said pins of the plates. The partition wall can thus assume a variety of polygonal or arc-shaped patterns with no need of being anchored to the floor or to the ceiling.
