Abstract

L'invention concerne un ensemble d'éléments de mise en prise (101, 102) qui comprennent chacun une feuille de base (10) et un ensemble (50k) de crochets en forme de J (50), chacun des crochets en forme de J (50) ayant une section verticale (50a) qui s'élève à partir de la surface principale (10a) de la feuille de base (10) et ayant également une section d'arc (50b) qui s'étend en une forme d'arc à partir de la section verticale (50a). L'ensemble (50k) comprend des rangées (FL) de crochets en forme de J, chacune des rangées (FL) comprenant des crochets en forme de J (50) agencés à des intervalles prédéterminés dans la direction d'axe Y. Les rangées (FL) de crochets en forme de J sont agencées à des intervalles prédéterminés dans la direction d'axe X perpendiculaire à la direction d'axe Y. Des crochets en forme de J (50) de l'un des éléments de mise en prise (101, 102) peuvent être insérés entre des rangées (FL) adjacentes de crochets en forme de J de l'autre élément de mise en prise (102, 101). Lors de la venue en prise des éléments de mise en prise (101, 102) de l'ensemble les uns avec les autres, chacun des crochets en forme de J (50) de l'ensemble d'éléments de mise en prise (101, 102) peut tomber élastiquement dans les directions opposées dans la direction d'axe X et venir en prise avec un autre.
