1. Suspending device and supplementary means of radial expansion to be placed in a hole in a wall or other partition, a tubular suspending device, split and of constant thickness over its full length but of variable diameter over its length, having on the inside of the area of entry a zone of embossment lines (2, 3) which can be forced outwards by the supplementary radial expansion facility (9) introduced by penetration into this area (2, 3) after insertion of the suspending device into the hole, characterized by the fact that the expansion facility (9) is of a length of the zone of the lines of embossment (2, 3), and by the fact that the suspending device also incorporates beyond the recessed part towards the outside at least one part (4a, 4b, 4c) of apparently larger diameter than that of the area of entry, formed by a widening out towards the exterior, such widening out forming an angle greater than nothing with the zone of entry, less than or equal to ninety degrees, and forming a collar against penetration by the device into the hole, a rounded (4a), straight (4b) or inclined (4c) collar, and by the fact that the device includes a part exterior to the wall (6), that is to say beyond the part forming the collar, which is arranged as a support or is capable of being fitted with a support device. |
