This rim 48 is furthermore connected to two radially outer tabs 50 which are diametrically opposite and which each comprise an opening for the passage of fastening means such as a screw or stud, which for example has to be crimped or welded/riveted. Tabs 50 are coplanar in a plane substantially perpendicular to the X axis.
  • Wall 46 comprises two through openings 52 in a longitudinal direction which are diametrically opposite in relation to the X axis. Openings 52 define portions of wall 46 which substantially form a H and comprise two lateral portions 46a connected together and at their middle by a median portion 46b.

  • This swelling 47 has an outer cylindrical surface extending as a prolongation of the longitudinal edges 44a of wall 44 of the body, which therefore has a diameter h2.

  • Annular rim 48 has an inner cylindrical surface of diameter u6. It has two first notches 56 which are diametrically opposite and extend in a first longitudinal plane, and two second notches 58 which are diametrically opposite and extend in a second longitudinal plane perpendicular to the first longitudinal plane.
  • First notches 56 are here located at the level of tabs 50. They each receive an attachment catch 60.
  • Each catch 60 is generally L-shaped and comprises a longitudinal part the lower end of which is connected to wall 46 and the upper end of which is connected to a transverse shoulder. Catches 60 are diametrically opposite and their shoulders are opposite each other ( Figure 6) . The closest distance between the shoulders of catches 60 is denoted u4.
  • These catches 60 are elastically deformable through flexion. Their upper ends are capable of being separated from each other. This is possible because of the elastic character of the catches and notches 56 in which they are housed, these notches being dimensioned to allow the aforesaid flexure, that is to say radial displacement towards the exterior of the upper end of each catch.
  • Second notches 58 pass through rim 48 radially. They are each laterally bounded by two guide walls 62a, 62b. Walls 62a, 62b extend in two planes parallel to the X axis.

  • Walls 62a, 62b extend radially towards the interior of rim 48 to form projecting teeth 64.
  • the closest distance between teeth 64 of walls 62a, 62b is denoted u5.
  • u6 is greater than u5.
  • - openings 52 in member 18 have shapes matching those of hooks 28 and excess thicknesses 34 of member 20; for example rl, r2 and r3 are respectively smaller than u2, ul and u3; body 36 is configured to slide longitudinally within member 20; for example hi is smaller than d2 ; branches 40 are designed to adopt their deployed position when they are housed in orifices 32 in the unstressed state; in this position teeth 40a of branches 40 project outside member 20, that is to say h2 is greater than dl; the width of branches 40 is preferably smaller than that of r4 of orifices 32,
  • the plate of the metal element or magnet 22 is intended to be housed within rim 48 and member 18; for example u6 is greater than LI and L2, and L3 is smaller than u5; L2 is also greater than u4 so that the plate can be held back through elastic snap-fastening by catches 60,
  • the plate is also configured to be mounted between hooks 28 of member 20 by elastic snap-fastening, the hooks being intended to engage notches 24 in the plate; for example F is greater than E and M is greater than D and L3 and smaller than LI .
  • Figures 8 to 11 illustrate a process for assembling fastener 10 described above.
  • a first step illustrated by Figure 8 comprises engaging body 36 of fastening member 18 in actuating member 20, so that this body 36 passes through member 20 longitudinally.
  • Members 18, 20 are positioned longitudinally with respect to each other so that hooks 28 are located above the transverse plane passing through tabs 50 and the upper end of rim 48. In this position folding member 26 extends around branches 40 and stresses them into their folded position. This operation can be performed manually or by a machine.
  • a second step illustrated in Figure 9 comprises fitting the plate of the element or magnet 22 into hooks 28. In order to do this the plate is moved in translation in the aforesaid transverse plane, so that hooks 28 engage in notches 24 in the plate through elastic snap-fastening. This is made possible by moving hooks 28 aside because of the ability of portions of wall 30 to bend elastically radially outwards, by bearing on the aforesaid teeth of the plate, which form a hard point for the elastic snap fastening.
  • the third step comprises moving member 20 downwards, this movement being facilitated by branches 40 which stress this movement through elastic return.
  • the plate then bears against the teeth of catches 60 and slight pressure on the upper face of the plate makes it possible to engage the plate between catches 60 through elastic snap fastening.
  • the plate is then in the position illustrated in Figure 14, teeth 64 being engaged in notches 24 of the plate.
  • folding member 26 extends around base 42 of member 18 and the lower ends of branches 40.
  • the plate is housed within shoulder 46 and is held within it in the longitudinal direction through cooperation with catches 60.
  • thickness E is appreciably smaller than distance Z between wall 46 and the teeth of catches 60, which imparts a certain travel for movement in a longitudinal direction to the plate, and to member 20. The travel is equal to Z-E.
  • Figure 15 shows panel 12 which is of a general rectangular shape and comprises two substantially cylindrical studs 11 spaced a predetermined distance apart corresponding to the distance between the centers of the orifices in tabs 50 of fastener 10 on one of its faces, the lower face which is intended to be invisible to a user.
  • Figure 16 shows support 14 which here has a generally upside-down U-shape and comprises an upper wall incorporating a hole 16 for fitting the fastener.
  • this hole has a diameter or average radial extent which is greater than dl and smaller than h2.
  • a first step in the attachment process comprises securing attachment 10 to panel 10.
  • attachment 10 is positioned on the lower face of panel 12 so that studs 11 engage in the orifices of tabs 50 of the fastener.
  • fastening member 18 bears against the upper peripheral edge of its rim 48 on the lower face of panel 12 so that body 36 of that member and actuating member 20 project from this lower face.
  • Studs 11 can then be crimped or welded (for example by riveting) in order to secure the fastener onto panel 12.
  • Panel 12 can then be secured on support 14. It is offered up to support 14 in such a way that the X axis of fastener 10 is aligned with hole 16. The panel is moved in translation along the X axis until body 36 and actuating member 20 engage in hole 16 and branches 40 are elastically snap-fastened to the peripheral edges of the hole, the branches passing from a folded position to a passage within the hole to a folded position once they can resume their original position substantially without any stress below the hole ( Figure 18) .
  • Figure 18 illustrates a position in which panel 12 is secured on support 14. In fact branches 40 are in the deployed position, which prevents panel 12 from being removed, because their heads bear on the peripheral edge of hole 16 in support 14.

  • the manipulating member causes the magnet or metal element 22 to rise along the X axis, which has the effect of causing actuating member 20 to rise. Because of this branches 40 fold inwards and panel 12 can be withdrawn from the support because the heads of branches 40 no longer act together with the support.
  • Attachment 10 can therefore be dismantled using an external tool without being able to see the fastening zone.

Each of these notches therefore comprises a median bottom edge 124a which is substantially flat and side edges 124b which are also substantially flat and perpendicular to edge 124a.
