The base section of a toy (1) is T-shaped and has a straight main branch (2). This has a bulge (3) near its free end that is symmetrical to its longitudinal axis (X-X). Two branches (4,5) extend symmetrically on either side of the axis and perpendicular to it. The branches are curved upwards and form a seat with the back part of the main branch (6). The base formed by the branches and the bulge of the main branch form a stable base. Holes (9,10,11) in the ends of the branches allow other pieces to be fixed to this element.
