Abstract

A rigid, disk-shaped plate (10) is journaled along one diameter on an axis transversal to the duct and projects through at least one hole in the duct wall. Two studs (20, 34) are attached to one side of the plate in respective, diametrically opposite areas of its periphery, and overhang out of the plane of the plate so that a peripheral rim of the plate is left free on both sides. An inner groove of a rubber gasket (42) shaped as an annular band is sheathed on the rim. The studs have coaxial, cylindrical bosses (30, 40) which are rotatably receivable in respective holes in the wall of the duct.
