Improvements in the joining systems of elements used in the manufacture of furniture, characterized in that the fixing bolts, housed in the holes previously drilled, are screwed on the inside of the furniture onto a self-adhesive part, constituted by a cylindrical bushing, with passage of internal thread to enable the screwed in that its upper base is equipped with a flat walled in which incisions are made, obliquely in relation to its diameter, drawing perpendicularly downward the outer fragments, forming pointed appendages, suitable to penetrate perpendicularly in the material to be joined, by means of the simple traction exerted by the bolt when being screwed.
