A fixing device which can be fixed to a surface such as a ceiling and receive a perforated section comprises a plate for fixing it to the surface and a support for receiving the perforated section. The support has a wall substantially perpendicular to the plate and at least two claws with the same orientation which cooperate with corresponding perforations of the perforated section. The wall includes a precut locking lug which can be bent into another perforation and cooperate with an edge of that perforation to immobilize the perforated section against movement in translation.

The invention claimed is: 1. A fixing device adapted to be fixed to a surface, comprising: two fixing lugs for fixing the fixing device to the surface; and a support having at least three walls defining an interior space, each of said at least three walls being integral with and substantially perpendicular to said two fixing lugs, a first wall of an opposing pair of said at least three walls having plural first claws that are bent into the interior space along a first fold line and a second wall of said opposing pair having plural second claws that are bent out of the interior space along a second fold line parallel to the first fold line, at least one of said first and second walls having a locking lug that is bent along a third fold line that is perpendicular to the first fold line. 2. The fixing device of claim 1, wherein the interior space has a longitudinal axis perpendicular to said two fixing lugs, and wherein the third fold line is parallel to the longitudinal axis. 3. The fixing device of claim 1, wherein said support has four of said at least three walls and wherein said support has one corner at which an adjacent pair of said four walls are separated by a gap. 4. The fixing device of claim 3, further comprising a perforated section that is generally U-shaped, said section having a base that is in said gap and abutting one of said four walls other than said opposing pair of walls, said section having a first arm that is inside the interior space and that has first perforations in which said first claws are received and a second arm that is outside the interior space and that has second perforations in which said second claws are received, said locking lug being received in one of said first and second perforations. 5. The fixing device of claim 3, where said support has three corners at which adjacent ones of said four walls are directly attached to each other. 6. The fixing device of claim 3, wherein said gap extends along an entire length of said support and wherein said adjacent ones of said four walls that are directly attached to each other at said three corners are directly attached to each other along the entire length of said support. 7. The fixing device of claim 1, further comprising a perforated section having a first arm that is inside the interior space and that has first perforations in which said first claws are received and a second arm that is outside the interior space and that has second perforations in which said second claws are received, said locking lug being received in one of said first and second perforations. 8. The fixing device of claim 1, wherein each of said first and second claws is also bent along a fourth fold line parallel to and spaced from respective ones of said first and second fold lines, so that a distal end portion of each of said first and second claws is parallel to a respective one of said first and second walls.
