A support device comprises at least one connection means (2) having a support means (4) and associable to a corresponding elongated prop means (5) and assigned, in an operative condition, to be vertical or nearly vertical. The side outer surface (51) of the prop means (5) has straight lines generatrix and parallel in respect to the longitudinal axis of the same prop means (5). The connection means (2) includes a cavity whose inner surface (21) is complementary shaped and almost equal to the shape of a portion of the outer surface (51) of the prop means (5) and has identical transverse dimensions or slightly bigger than those of this latter outer surface (51). This inner surface (21) has a lateral opening (22), inclined in respect to the straight lines generatrix of the inner surface (21), sufficient wide to allow the passage of the prop (5) and whose projection onto a plane perpendicular in respect to said straight lines generatrix of the inner surface (21) is smaller than the corresponding transverse section of the prop means (5). The connection means (2) has also a coupling (23) for the support means (4) and approximately oriented parallel in respect to the lateral opening (22) and approximately perpendicularly to the straight lines generatrix of the inner surface (21).
