A saddle for supporting elongated bodies has a body with a quadrangular section, on the opposite sides of which wedge-inserted coupling members are provided, to couple the saddle with another saddle, so as to have the reciprocal stacking of these saddles on a support. A saddle according to the invention offers the advantage over known saddles of being stacked on previously installed saddles due to the presence of incorporated members which allow their connection, without resorting to the use of tools or similar auxiliary equipment.
