摘要

The shutter (10) has side cheeks (14, 16) comprising an inner face that is directed towards an interior part of a casing (12). Connection legs comprise a free end, and an external support area and an internal support area come in contact between two opposite internal walls of a tubular part (22). The external support area extends towards the free end of the connection legs and converges towards the internal support area to tilt two side sections (18, 20) relative to the connection legs when the free end of the connection legs is engaged between the internal walls of the tubular part.
