The seal (10) has projecting ridges (23) connecting confinement flanges to a central hole (13), where the seal has a pivot angle of 90 degrees in a plane (YZ) that is perpendicular to a longitudinal axis. The flanges are folded back by foldable shoulders (27-30) deformed toward concave portions of insertion recesses (21, 22) from a normal operating state to a release state. The ridges are supported against an abutment section (33) of each recess. The abutment section is located between the hole and the flanges, and is arranged opposite to the flanges. The confinement flanges are formed of an inside top confinement flange (17), an outside top confinement flange (18), an inside bottom confinement flange (19) and an outside bottom confinement flange (20). An independent claim is also included for a weatherproof framework. |
