<p>The device has an additional fixing profile (600) positioned between opposite inner faces (311, 321) of outer and inner profiles (310, 320) of hollow profiled sub-assemblies (300) forming slats (L1-L3) of a shutter, where the slats are made of aluminum or equivalent alloy. The additional fixing profile is made of polyamide. The additional fixing profile adopts an H-shaped profile between branches, which are positioned in longitudinal bearing faces arranged on both sides of connection surfaces in longitudinal edges of the outer and inner profiles of the subassemblies.</p> |
