<p>A tensioning apparatus is described comprising a plurality of support centerings (13; 57; 157) for a covering tarpaulin adapted to slide on the edge of a top body, a cable (10; 40; 140) mounted on the top body able to draw back and/or forth on the top body at least a centering. The invention proposes that at least two cable ends or extremities (P1, P2) are constrained to a centering so that said ends or extremities are able to draw it back and forth. An easy and cheap system descends for tensioning the cable.</p> |
