Abstract: The invention relates to a holding device (1) by which preferably multilayer cushions inflatable by air pressure can be fixed to a structural member, e.g. for producing a light-permeable and heat-insulating ceiling. For this purpose, the holding device (1) according to the invention comprises one or several piping profiles (4, 5) for receiving a peripheral thickening (42) of the cushions (2, 3). After the peripheral thickening has been fixed, the piping profiles (4, 5) are located in one or several receiving spaces (8, 9) of the supporting profile (6). In order to secure the piping profiles (4, 5) against loss a top profile (7) is fixed to the supporting profile (6).
