- the inflection of the retaining tab 28 is formed by a bend 28G.
- the retaining tab 28 forms a non-zero angle ⁇ with the wall element 20, 22.
- the retaining tab 28 Between the elbow 28G and the free end 28F of the retaining tab 28, the retaining tab
- the free end 28F of the retaining tab is directed toward the other wall member and is closer to the other wall member than the bend 28G.
- the insertion ramp 28C is in a plane secant to the longitudinal direction X.
- the retaining tab 28 has a width L which decreases towards the free end 28F of the retaining tab 28.
- the insertion ramp 28C has a maximum height Flmax in a plane perpendicular to the fastening base 16 which is less than or equal to 90% of the maximum width Lmax of the tab. retaining 28, preferably less than or equal to 80%.
- the minimum value D24min of the passage distance between the two wall elements 20, 22 is defined between the retaining tab 28 of the wall element 20 and the wall element 22, or conversely between the retaining tab 28 of the wall element 22 and the wall element 20 and more particularly between the free end 28F of the retaining tab 28.
- the maximum amplitude of the Amax inflection of the retaining tab 28 may be equal to 5 mm, the maximum distance D24max between the two wall elements
- the minimum value D24min of the passage distance between one of the two retaining tabs 28 of one of the wall elements 20, 22 and the other wall element 22, 20 may be equal at 3 mm and the diameter D12 of the ring 12 that the retaining device 10 is configured to retain may be equal to 7 mm.
- the maximum amplitude of the inflection Amax of the retaining tab 28 is equal to 62.5% of the maximum distance D24max between the two wall elements 20, 22, the minimum value D24min of the distance of passage between one of the two retaining tabs 28 of one of the wall elements 20, 22 and the other wall element 22, 20 is equal to 37.5% of the maximum distance D24max between the two wall elements 20, 22 and the minimum value D24min of the distance between the two retaining tabs 28 of the retaining device 10 is equal to 42.9% of the diameter D12 of the rod 12.
- the retaining tab 28 is rectilinear, seen from above.
- the materials used to produce such a device may be a plastic material, for example polyethylene (PE), polyoxymethylene (POM), polyamide (PA), rubber having a certain rigidity, a metallic material, for example steel, or aluminum, a composite material, for example a reinforced plastic material, for example with glass fibers and / or carbon fibers or a mixture of these materials, for example different plastics and / or a plastic material with a composite material.
- the methods used for the manufacture of such a device may be, for example without limitation, a plastic injection process or cutting / stamping a metal sheet.
- the device can be formed in one piece.
- the retaining device 10 comprises a length XI of approximately 40 mm, a Y1 width of about 30 mm and a height ZI of about 15 mm, the retainer 10 thus having a small footprint for a rod 12 of a size between 3 and 15 mm.
- Those skilled in the art can easily vary the dimensions of the retaining device 10 according to the dimensions of the rod 12.
- the retaining device 10 may be used for fixing or guiding cables and / or tubes, for example in the automotive field or in the building field, the retaining device 10 allowing reliable fixing. resistant to pulls, and which cables and / or tubes can be extracted without damaging the cables and / or tubes and / or without breaking the restraint.
- the retaining device 10 may comprise object attachment elements 14 attached to the fixing base 16.
- the various embodiments could have through-openings 18 in the part of the fastening base 16 delimiting the retaining cavity 24.
- the portion of the fastening base 16 delimiting the retaining cavity 24 of the embodiment of FIGS. 9 to 12 could be solid and therefore not comprise through openings 18.
- the shape of the fastening base 16 is not limited to the forms presented in the various embodiments described.
- the shape of the fastening base 16 can be modified to fit the object 14 on which the fastening base 16 is assembled and / or fixed.
- the retaining device 10 can be fixed to the object 14 by overmoulding the object 14 on the fastening base 16, by mechanical clamping of the fastening base 16 on the object 14, for example with clamps passing through the through openings 18, by passing screws or nails through the through openings 18 and / or by changing the fixing base.
- the wall element 20, 22, in a plane perpendicular to the fastening base 16 and parallel to the longitudinal direction X has a general shape of elongate rectangle in the longitudinal direction.
- the general shape of the wall element 20, 22 may be a circular arc, in the form of an arch, so that the arc or the arch is formed by a portion of the retaining tab 28.
