Description

The invention relates to an elastic retaining clip for fastening

of tubular elements of fo:

  cylindrical, especially pipes or

  cables, of variable diameters, on

  Harbor. This retaining clip consists essentially of

  two side walls connected together according to a

  U-shaped girding via a base plate, and each having, at their free end, flexible molded retaining tabs oriented towards the center of the inner retaining jig.

  forming substantially one V, as well as two other walls of ap-

  and flexible hoses laterally limiting the inner retention template, which originate in the upper part of the side walls and which are oriented downwards also forming a y, the lower edges of said bearing walls terminating in this case substantially at center between the support edges of the retaining tab and the

base plate.

  The flexible retaining tongues present here the advantage of moving slightly apart during the introduction by pressing a cable into the staple, then to resume by natural elasticity their primitive positior, taking in this case the support at their application edges pretty much radially on the

  outer surface of the cable and then being essentially

  allowed for compression. As a result, the holding force of

  the staple is significantly larger than the effort of

  which is the force that is necessary to apply to press in the staple a tubular element

re of cylindrical shape.

  The cables are also closed

  flanged in position on both sides by the action of the

  kings of support, the said support walls adapting in this case

  easily to the diameter of the cable introduced.

  The retaining clip can thus be

  be used for a range of well-defined diameter values. It is however a pity that in the case of reduced diameter cable, a large part of the inner retaining jig is not used, namely the space between the support edges of the retaining tongues and the base plate. The object of the present invention is to give the retaining clip a configuration such that it

  it is possible to obtain a more complete filling of the gabal

laughs inside restraint.

  According to the present invention, this object is achieved by providing, in the center of the base plate or bottom of the clip, parallel to the support walls and to the side walls, a

  chute for supporting laterally the tubular element cy-

  lindrique the smallest to fix in position. By this simple.

  the range of use of the retaining clip is increased in such a proportion that, if necessary, two small diameter cables can even be attached by the staple

  in superimposed position, the thickness corresponding to the

  given by the two conjugated thin cables not in this case not to be greater than the greatest permissible unit cable thickness for the retaining clip considered

  SOE. In this case, the lateral support walls function

  at the same time the retaining tabs for the cable are

  finding in the lower position.

  To ensure that she can

  certainty to assume its lateral support function, the government

  burbot is raised in such a proportion that the element tu-

  cylindrical bile is supported at least a quarter of

its periphery.

  But the wall of the chute can also

  be in the form of two oblique

  symmetrically arranged with respect to each other on the bottom, which together form an aperture angle α of about 90, so that the small diameter cables are held in position in a sort of support vee. This particular configuration of the chute is suitable

  particularly well for the manufacture of the staple for

  shot of a metallic material, because it is then enough to cut with the press in the bottom of the staple of the small tongues,

  which will only have to be relieved.

  The sketches illustrate two examples

  of the retaining clip, which are going to be

  in more detail in this continuation of this description. The differences

  The retaining clip consists essen-

  linked to it by giving a U-shaped configuration, and at the free ends (7) of which are molded, flexible retaining tongues (4) which are oriented towards the center of the inner jig di 3O retaining (3) of the staple forming a V. These tabs are close to one another in the center of the inner retaining jig (3) but remaining spaced from each other in the proportion of a value 's' which is smaller than 1 smaller cylindrical tubular element diameter than one can have. The retaining tabs (4) are,

the staple (see Figures 3 to 5).

  To carry out the clamping in position of the cylindrical tubular elements to be maintained in the cones

  meters of different elements, two further flexible support walls (8) have been provided which, starting from the upper zone of the side walls (2), are oriented towards the

  In the center of the bottom (1) is provided,
