Sistema para asociar dos elementos por sus paredes flexibles adyacentes

The invention concerns a system for associating two elements (11) by their adjacent flexible walls (11 b), said system comprising: said two walls and at least two orifices (14) formed in each of said walls to be aligned two by two when said walls are in a juxtaposed position; a pair of tabs (15) being operable to be arranged next to the aligned orifices 14 respectively on one side of juxtaposed walls 11b, mutual coupling means (16, 17) of the tabs (15) adapted to be engaged through said aligned orifices in a position wherein said walls are plated between said tabs; the couplings means (16, 17) comprising a pin (16) provided on a tab (15) and a hole (17) provided on the other tab (15) and operable to be disposed respectively through and next to the aligned orifices (14) when said tabs are arranged on either side of the juxtaposed walls (11 b), a pin (16) of a tab (15) being arranged to be irreversibly coupled within a hole (17) of another tab (15) in a position wherein said walls are plated between said tabs.
