  • the core is advantageously produced from a generally rectangular metal strip further limited by an outer longitudinal edge which extends parallel to the inner longitudinal edge and which is suitable for being situated outside the tubular wall.
  • This outer longitudinal edge can be flush with or protrude externally from the tubular wall.
  • the tubular wall includes a cover and the core a cutout placed opposite this opening to allow the establishment of a connecting piece, in particular a tubing.
  • This cut and this opening then cooperate to allow the establishment and maintenance of this connecting piece during the brazing operations.
  • the core has a minimum width always greater than the thickness of the tubular wall.
  • the fixing lug is placed in a position and an orientation chosen with respect to the core.
  • fixing tab itself has a configuration adapted to the particular use for which it is intended.

  • the manifold 10 has a tubular wall 12 provided with aligned holes 14 each having the shape of an oblong passage.
  • the manifold 10 is further provided with a longitudinal slot 16 which extends parallel to the axis XX and which is delimited by two longitudinal edges 18 and 20 parallel to each other and parallel to the generating the tubular wall 12. These two longitudinal edges define between them the width L of the slot 16.
  • the slot 16 extends over the entire length of the manifold 10 (shown partially).
  • the tubular wall 10 is advantageously formed by rolling and punching a metal strip, for example made of aluminum or aluminum alloy.
  • FIG. 2 shows a fixing piece 22 comprising a rectangular core 24 extended laterally, at one end, by a fixing tab 26.
  • the core 24 notably comprises an inner longitudinal edge 28 and an outer longitudinal edge 30 which extend parallel to each other.
  • the fixing tab 26 extends in a direction generally perpendicular to the length of the core 24. It is further provided with a hole 32 intended for the passage of a fixing member (not shown) such as a screw. or the like.
  • the fixing piece 22 constitutes a one-piece assembly which can be obtained either by cutting a metal strip, or by molding or extruding a metallic material.
  • the fixing piece 22 is advantageously made of the same metallic material as the manifold 10, that is to say preferably made of aluminum or aluminum alloy.
  • the core 24 has a thickness E which is slightly less than the width L of the slot 16. It also extends over a length which corresponds to that of the slot 16, that is to say, in the example, over the entire length of the manifold 10.
  • the core 24 is intended to be inserted and threaded inside the manifold 10 passing through the slot 16, as shown in FIG. 3.
  • the fixing piece 22 is then immobilized in a position in which the longitudinal edge interior 28 extends parallel to the generators of the tubular wall 12.
  • the edge 28 is situated practically in alignment with the axis XX.
