Claim 1

A hanging device for hanging straps out of resilient plastic material adapted to be a screen or a curtain for closing apertures, partitioning or insulating premises, which comprises: an elongated hollow girder in the form of an inverted U opening downwardly, and rigid strap hanging members having lower parts, each of said parts being secured to the upper end of a strap, each hanging member (3) comprising at its upper part, several equidistantly spaced openings (6) each beginning at the upper edge of the hanging member and being prolongated interiorly towards at least a same lateral direction so as to constitute spaced hooks arranged for engagingly cooperating with parallel and equidistant transveral complementary members sustained by the girder (20;8), said complementary members having a thickness lesser than the width of said openings (6) and extending transversally inside said girder (1,1') above the plane of the lower edges of said girder, said transversal complementary members being made of a single piece with a hooking structure introduced within the girder (1), wherein said hooking structure comprises a rod (2) formed with a series of U-shaped alternate folds extending in a same plane, wherein the grider (1) has wings (10), the end portions of which are folded inwardly in the direction one towards each other and further extend slightly upwardly inside the grider while being separated one from each other, the transversal complementary members (2) bearing upon the inner edges of said folded and inwardly extending wings.
