  • the invention makes it possible, thanks to the particular configuration of the first hole 27, to easily conform a helical protection sheath and to extend this sheath bearing against the longitudinal central bore.
  • this configuration reduces the stress concentrations at the level of the junction between the portion of the protective sheath housed in the first hole 27 and the portion of this sheath extending in the longitudinal central bore 15.
  • the first hole 27 and the second hole 37 house a part of the protective sheath 35 which can be described as “guided”, as opposed to a “free” part of this sheath, which free part extends between these first 27 and second 37 holes, in the longitudinal central bore 15.
  • the partial guide of the protective sheath 35 performs a helical conformation of the protective sheath 35, in particular in its free portion.
  • This free portion could, for some very particular applications, be maintained, in its helical form, in the longitudinal central bore 15, for example by means of an epoxy resin.
  • the particular arrangement of the first 27 and second 37 holes is advantageous.
  • the angle of bias A2 has been defined in the tangent plane P2 to the longitudinal central bore 15 at the first intersection location 31.
  • the invention could be equivalently defined with an angle of inclination A3 defined in a plane perpendicular to the median plane P1 and containing said first location 31.
  • the angle of bias A3 is equivalent in this case to the projection of the angle of bias A2 in said plane perpendicular to the median plane P1.
