Abstract

L'invention porte sur un système de clôture modulaire, lequel système comprend un premier profil comprenant une lame (18) et une bride (20) qui s'étend transversalement à partir d'une extrémité de la lame dans une première direction. La lame définit une partie fraisée (24) qui s'étend vers la première direction, une première ouverture (26) dans la partie fraisée (24), et une seconde ouverture (28). Des seconds moyens de liaison (40) dimensionnés pour traverser la seconde ouverture (28) fixent le premier profil à un profil adjacent selon un agencement dos à dos. Un support (16) peut être fixé à la lame (18) par l'intermédiaire des premiers moyens de liaison (40), comprenant un col dimensionné de façon à traverser la première ouverture (26) et une tête dimensionnée de façon à être reçue à l'intérieur de la partie fraisée (24). Le support (16) est formé de façon à s'étendre vers la bride (20), et définit un bord s'étendant sensiblement le long de la bride (20), ce bord définissant au moins deux dents (36) pour capturer au moins un segment allongé d'un panneau de clôture entre : (i) la dent (36) ; et (ii) la bride (20) et/ou la lame (18) de façon à fixer le panneau de clôture (14) en place par rapport au premier profil.
