Definitions

• the invention relates to the technical sector of fixing devices and relates more particularly to a device for securing an assembly screw to an element to be fixed on another element.
• the invention finds a particularly advantageous application in the automotive field, for example for fixing a cable on its sheath stop.
• the object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.
• the problem to be solved by the invention is to be able to fasten an assembly screw to an element to be fixed on another element, with, as a first objective, to make the screw prisoner of the element and, as another objective, to use a conventional screw having a threaded bearing whose nominal diameter is greater than the diameter of the screw rod.
• the device according to the invention comprises an anti-creep ring intended to receive the screw and one of whose ends has arrangements capable of delimiting, before engagement of the ring in a housing of the element in front of to be screwed, a circular zone of diameter greater than the nominal diameter of the threaded bearing surface and, after engagement of said ring in said housing, a circular zone of a diameter smaller than that of the nominal diameter of the threaded surface but greater than that of the rod so as to abut the said seat and imprison the screw in the ring, while allowing a limited displacement of said screw, in the ring.
• said ring has arrangements capable of allowing it to elastic deformation under the effect of its engagement in the housing of the element, said deformation corresponding to the decrease in the diameter of the circular zone.
• the arrangements of the ring capable of delimiting a circular zone of variable diameter by elastic deformation are constituted by a light formed over the entire length of said ring, while the abutment effect is obtained by at least two pins formed overflowing one of the ends of the bore of the ring.
• the two lugs are diametrically opposed and at least two lugs are obtained by cutting and folding the ring.
• the length of the screw is greater than the length of the ring, the threaded bearing being formed at the end of the screw rod.
• the length of the ring substantially corresponds to the depth of the housing of the element.
• the device according to the invention finds an advantageous application in the field of the automobile for fixing a cable on a sheath stop, without thereby excluding other applications not only in the automotive field, but also in other sectors.
• FIG. 1 is a perspective view of an embodiment of the anti-creep ring according to the invention.
• FIG. 2 is a longitudinal sectional view showing the engagement of the screw in the anti-creep ring, and before mounting in a housing of the element to be fixed.
• FIG. 3 is a view corresponding to Figure 2 after engagement of the screw assembly and anti-creep ring in the housing of the element.

• FIG. 11 is a view corresponding to FIG. 10 showing the positioning and positioning of the element equipped with two anti-creep screw / ring assemblies on a support and before fixing said element, the screws remaining trapped in the 'element.
• Figure 12 is a view corresponding to Figure 1 1 showing the attachment of the element on the support.
• the problem is to secure an assembly screw (1) to an element (2) to be fixed on another element (3).
• the rod (1a) of the screw (1) has a threaded bearing (Ib) whose nominal diameter is greater than the diameter of said rod (1a).
• the device according to the invention comprises an anti-creep ring (4), one end of which has arrangements capable of delimiting a circular zone of diameter (D) greater than the nominal diameter (D1) of the threaded bearing surface (1b). ). As shown in Figures 1, 6, and 7, this diameter (D) can be obtained by at least two lugs (4a) and (4b) formed in overflow of one end of the bore of the ring (4). ).
• the lugs (4a) and (4b) are diametrically opposed.
• the ring (4) has 4 lugs (4a, 4b, 4c, 4d) offset by 90 °.
• these lugs can be obtained by cutting and folding the ring.
• the ring (4) further has arrangements adapted to allow it to elastic deformation under the effect of its engagement in a housing (2a) of the element (2).
• this elastic deformation capacity is obtained by a light (4e) formed over the entire length of the ring and according to its generators.
• This light (4th) may for example have a median area of reduced width symmetrically connected to two end zones of greater width.
• the screw (1) After engagement of the ring (2) equipped with the screw (1) in the housing (2a) of the element (2), and following a tight fitting of said ring in said housing, the latter is deformed so that the circular zone delimited by the lugs (4a, 4b, 4c, 4d) and initially of a diameter (D), has a diameter (D2) greater than the diameter (D3) of the rod (1a) but smaller than the diameter (D1) of the threaded surface (1b) to act as a stop at said reach.
• the screw (1) can therefore be moved in the ring (4) between an abutment position of its head (1c) with the element (2) and a thrust position of the threaded bearing (1b) with the lugs (4a, 4b, 4c, 4d).
• the length of the screw (1) is greater than that of the ring (4).
• FIGS. 2 to 5 show the implementation of the device according to the invention for assembling the two elements (2) and (3).

• the screw (1) After engagement of the screw (1) / ring (4) assembly in the housing (2a) of the element (2), the ring (4), under the effect of a tight fitting in said housing, is deformed elastically so that the circular zone delimited by the lugs (4a, 4b, 4c, 4d) has a diameter (D2) smaller than the diameter (Dl) of the threaded bearing surface.
• This diameter (D2) being greater than the diameter (D3) of the rod (la)
