The grid comprises a series of modules which are juxtaposed and coupled together laterally. It is characterized in that each module has, on its two opposite lateral faces, the formation of individual pairs of elastic fingers, with the special feature that the pair of fingers of one side has individual pegs and the pair of fingers of the other side has individual orifices in which the said pegs fit, giving rise to the elastic lateral coupling of the modules constituting the grid. <IMAGE>
