Abstract

La présente invention concerne des anneaux d'ancrage. Un anneau d'ancrage destiné à réaliser un point d'ancrage sur un élément tubulaire en plastique, est constitué par une pièce massive 4 délimitée par l'intersection de deux plans obliques parallèles avec un profil comportant une partie cylindrique 6 dont le diamètre interne est égal au diamètre extérieur du tube plastique 1 et une saillie latérale 7 permettant l'accrochage. Cet anneau d'ancrage est utilisé principalement pour les couvertures de protection des cultures.
