Expanding anchoring device (10) and relative method of production. The anchoring device (10) is attached to a wall (15) and comprises a tubular body (11) provided with a plurality of deformable elements (19), and a spreader element (12) which is arranged inside the tubular body (11) and moved axially in order to determine the elastic deformation of the deformable elements (19). Each deformable element (19) is made in a piece from the tubular body (11) and comprises, at one end, stopping teeth (25) which prevent the spreader element (12) making an axial movement towards the outside of the tubular body (11). <IMAGE>
