A component to be mounted on an opening (16) of a wall (19) comprises a main body (2, 3) and a flexible skirt (13) extending around the main body (2, 3). Said skirt (13), in relation to an axis (Z) running through the main body (2, 3), has a main section (14) that extends radially outward and towards a contact plane that is perpendicular to the axis (Z). The main section (14) of the skirt (13) is connected to the main body (2, 3) by a base section (26) which extends radially outward from the main body (2, 3) in a line running along the axis (Z), and away from the contact plane. |
