<p>The device is comprised of a thin element (1) configured like a flexible material sheet which may be extended flat on the ground, and of a plurality of flexible ties (2) which are attached on the one hand to the pheriphery of the element and, on the other hand, to a unique junction part (3) fixed to the article (4) to be protected against thefts. The element (1), once extended on the beach, is covered with a ballast-forming sand layer. Thereby, any traction exerted on the protected article will result in the back-folding of the element (1) around the ballast by the tightening of the sides of the element (1) so as to form a burden opposing an important resistance to the traction effort exerted on the article (4) to be protected.</p> |
