An assembly (MC) is described constituted by a flat support element (20) and a ladder (10) with at least one peg (14), wherein the support element comprises a flat surface (22) and a seat (28) engageable when needed by the peg so that the support element remains integral with the ladder and thus allows the leaning of an object. The peg has circular cross-section and the seat (28) has a shape substantially complementary to the peg and such that it can engage it, and the support element comprises a second seat (30) engageable by a transverse bar (38) adapted to abut against the sides of the ladder and prevent a relative rotation of the seat with respect to the peg. |
