The device has an integration unit integrating a lining part (5) having centrally hollowed flat top hemispherical cap shape, with a smoke evacuation pipe (1). A maintaining unit (11) maintains the part at suspended state, with the pipe in a configuration in which an axial through passage (6) of the part extends coaxially with the pipe. The integration unit is formed of an attachment i.e. flange (8), a magnet (9) and a ferromagnetic part (10) that is in the form of continuous/discontinuous surface, where the magnet and the ferromagnetic part couple connection units (11A, 11B) by magnetization. |
