Abstract
This device for the installation and retention of a shutter plate (11) for an opening (7) comprises a carrier ring (21) provided with an inner channel (22) with an inclined face (23), positioned within which are clamping wedges (25) which bear upon the periphery of the shutter plate (11) and which, under the action of locking screws (27) which interact with the carrier ring (21) move individually within the said channel in a downward radial direction so as to exert a compressive force on the said shutter plate.
