Patent ID: 8336266

Claim:
A fixing system for false stretched walls, constituted by a flexible sheet hooked by borders to a frame fixed to the wall or ceiling of a room, said frame comprising a stringer formed by butted profiles comprising at least two parallel flanges, comprising an external flange and an internal flange, said external flange comprising on one side means for fixing to the wall or ceiling and on an other side a shoulder extending perpendicularly to an interior of the stringer in the direction of the room, said internal flange being connected to said external flange by a web located at an end thereof and extending to an other end beyond the shoulder of said external flange to form a peripheral support of the sheet which is stretched substantially perpendicularly to said internal flange by said borders fitted with a hook in a general shape of a harpoon inserted between the flanges of the stringer and formed by a first section which is connected to the sheet and a second section folded back on the first section wherein an end bead is supported on the shoulder of the external flange, wherein said end bead of the harpoon comprises a disconnection lip coming perpendicularly from a support zone of said bead on the shoulder providing hooking of the sheet on the stringer and extending under said shoulder into a gap between said external flange and said internal flange of the stringer such that said lip serves as a lever for an application tool, enabling the end of the harpoon to be pushed out of the shoulder without the tool penetrating into the stringer, to detach the sheet from said frame.
