The fastening device 1 comprises at least one fastening collar 6 adapted to be engaged at least partly around the post 3 and to cooperate, by means of connecting members 7, with a fastening rail 8 at least partly permanently attached to on the back 9 of the panel 2 and for associating said panel 2 to the post 3.

The post 3, whose cross section is generally circular, is preferably of the type conventionally vertical tubular upright.

The term "generally circular" here designates that the post has a cross section that may be wholly or partially in the form of a circle, an ellipse or a closed planar curve having no right angle.

The panel 2 is preferably associated with said post 3 by means of two sets of fixing collar 6 - fixing rail 8, arranged one above the other along the post 3.

With reference to FIG. 2, each fastening rail 8 preferably consists of a profile whose cross section is in the overall shape of C and which comprises a core 81 and two flanges 82 each extending substantially perpendicularly from one to the other. longitudinal edges of said web 81, said web 81 and said wings 82 defining an inner housing 83.

Each fixing rail 8 is positioned on the panel 2 by putting the web 81 in contact with the back 9 of said panel 2, then it is secured permanently by any appropriate means such as, for example, riveting. The rail 8 comprises, on its face opposite to the core 81, a longitudinal slot 84 opening on one side to the outside and the other in said inner housing 83, the width of said slot 84 being less than the distance separating the two wings 82 of said rail 8 and thus to the width of the inner housing 83.

The inner housing 83 and the slot 84 open preferably at each of the free ends of said fastening rail 8, which is preferably an extruded section of light alloy, preferably aluminum.

With reference to FIGS. 3 to 7, the fastening collar 6 comprises a generally U-shaped elastically deformable body 61 comprising a core 61a having a generally semicircular shape and two wings 61b, 61c each coming from one of the free ends of said core. 61a and extending apart from each other so that said body 61 is generally U-shaped slightly flared (see Figures 4 and 5) to facilitate its establishment around the pole 3 according to Figure 4.

The fastening collar 6 also comprises two fastening tabs 62, each one coming from the free end of one of the wings 61b, 61c of its body 61 and extending towards the outside of said body 61 so as to define a plane P of contact on which the associated fastening rail 8 is adapted to come into contact.

Furthermore, the fastening collar 6 comprises, on the inner face of each of its wings 61b, 61c of its body 61, a retaining bead 63 allowing said body 61 to be clipped onto the post 3, elastically enclosing the latter between its web 61a and wings 61b, 61c and the retaining stubs 63 arranged vis-à-vis (see Figure 4).

Here the term "inner face" of a wing 61b or 61c or the core 61a the face located on the side of the space between said web 61a and wings 61b, 61c. The skilled person will have no difficulty to size, according to the dimensions of the post 3, the body 61 of the clamp 6 and its retaining heels 63 to ensure effective clipping of said clamp 6 on said post 3.

In addition, the body 61 also comprises on each of its fastening tabs 62 a retaining rim 64 coming from the plane P, extending outwardly of said body 61 and being able to fit fit into the slot 84 associated mounting rail 8.

By "adjusted" it is meant here that the respective widths of the holding flange 64 and the slot 84 are such that once the retaining flange 64 is inserted into the slot 84, the panel 2 can not be easily disengaged from collar 61.

This feature is interesting because it ensures the maintenance of the panel 2 on the clamp 6, once the latter clipped on the post 3, which allows an operator to then put in place the connecting members 7 without the aid of a second operator.

According to an advantageous embodiment, for reasons of mechanical strength, each set "retaining heel 63 - holding flange 64" associated with one of the wings 61b or 61c is in one piece and formed by at least one tongue in the overall form of L, and preferably two tabs in the overall shape of L and parallel to each other, each tab being derived from the associated flanges 61b or 61c and associated bracket 62 (see FIGS. 6 or 7).

The fastening collar 6 further comprises adhesion means 65 making it possible to prevent said fastening collar 6, once clipped onto the post 3, sliding along the latter and pivoting about the longitudinal axis of said post 3. .

For this, the adhesion means 65 preferably comprise a notched crown disposed on the inner face of the core 61a of the body 61 of the fastening collar 6 (see FIGS. 5 or 7).

However, said adhesion means 65 may be of another type such as, for example, a magnetic ring, without departing from the scope of the present invention.

Finally, the fixing lugs 62 each comprise an orifice 66 passing through them from one side to the other and being able to cooperate with a connecting member 7, preferably of the bolt type, for securing the fastening rail 8 to the fastening collar 6, and therefore the panel 2 on the post 2.

With this configuration, it is clear that the joining of the panel 2 on the post 3 is particularly simple and fast and does not require the presence of two operators on the site of implantation.

Thus, once the post 3 erected and the panel 2 provided with at least one fixing rail 8, the operator must just clip at least one fastening collar 6 around the post 3 at the desired altitude and place the panel 2 against the fixing lugs 62 of said clamping collar 6 so that the fastening rail 8 bears against the plane P and the retaining flanges 64 are inserted into the slot 84 of said rail 8.

In this situation, the operator can then release the panel 2, take the connecting members 7 to simultaneously cooperate with the mounting rail 8 and the orifices 66 of said attachment lugs 62 and tighten the connecting members 7 to fix the panel 2 on the post 3.

According to a preferred embodiment, said orifices 66 are openings opening at the free end of the associated attachment lug 62 in order to allow easy positioning of the connecting members 7 without having to disassemble them or move the rail 8 apart. fastening of the fastening collar 6.

Indeed, insofar as the connecting members 7 are preferably bolts and comprise a screw and a nut not shown in the figures, the operator must simply slightly unscrew the nut, engage the head of the screw in the housing 82 of the fixing rail 8 by passing the rod of the screw through the slot 84 of said rail 8 and slide the bolt until it engages in the slot 66 of the associated bracket 62. Then the operator just has to screw the nut back onto the screw.
