Modulatable integrated system for connecting at least two cylindrical elements (9) composed of a rigid vertical rod (1) connected to at least three solid rings (2, 3, 4) capable of containing the cylinders and having analogous diameter, characterized in that the three solid rings are connected to the rigid rod (1) in a manner so as to form three separate levels that are equidistant from each other, parallel to each other and orthogonal to the axis of the rigid rod (1), and are arranged in a manner such that two of the solid rings (2 and 4) are perfectly superimposed.
