A soil erosion control device designed to be placed on or embedded in the ground comprises a lower portion (1) having anchoring elements and an upper portion (2) having elements for attenuating the energy of erosive fluids. Said attenuating elements include a rigid protuberant shell (5) and said anchoring elements have a water-tight base (3) facing the ground and subject to a first hydrostatic pressure which is lower than a second hydrostatic pressure acting on the top surface (4) of said anchoring elements and resulting from the erosive fluid pressure on the shell (5). The upper (2) and lower (1) portions are rigidly fixed to each other at least at their edges so that they define an inner space which can be at least partially filled with ballast (15) or with the material making up the anchoring and/or attenuating elements. Said material may be formed as a single piece therewith.
