A closure device for closing an opening (11) in a structure (10) such as a wall or floor. The closure device has a sealing assembly (33) formed by a first clamping body (35), a second clamping body (36), a disc-shaped deformable member (37) of sealing material, placed between the oppositely spaced first and second clamping body (35, 36), and clamping means (25, 26) for moving the first and second clamping body (35, 36) in a direction (z) relative to each other, for compressing the deformable member (37) when the first and second clamping body (25, 26) are moved towards each other. By this compression, the deformable member (37) expands in outward direction (r) transverse to the moving direction (z) of the first and second clamping body (35, 36) for engaging an inner surface (12) of the opening (11). The first and second clamping body (35, 36) and the deformable member (37) are shaped for deflecting the deformable member (37) along the moving direction (z) of the first and second clamping body (35, 36) when the deformable member (37) is compressed. |
