Abstract
The invention relates to a system for attaching false stretched walls made of a flexible sheet (1) attached by the edges thereof to a mini-stringer (3′), said edges being provided with a harpoon-type hook (11) inserted as a gooseneck between the two flanges of the stringer (3′) and including a first section (11a) connected to the sheet (1) and a second section (11b) folded on the first one, and having an end bead bearing onto a shoulder (8) of the outer flange (5) of said stringer, characterised in that the end bead of the harpoon (11) includes a disconnection lip (12) extending perpendicularly from the bearing area of the bead on the shoulder (8), and extending under said shoulder (8) in the gap of the stringer (3′) so that said lip (12) can be used as a lever for urging the end of the harpoon (11) out of the shoulder (8), without any penetration of an application tool in the stringer (3′), in order to easily dismantle said sheet (1).
