An anti-theft device having a thin element configured like a flexible material sheet which can be extended flat on the ground and a plurality of flexible ties which are attached to the periphery of the element and to a unique junction part fixed to the article to be protected against theft. The thin element is covered with a ballast-forming sand layer. Any traction exerted on the protected article will result in the back-folding of the element around the ballast by the tightening of the sides of the element so as to form a burden opposing the traction effort exerted on the article to be protected.
