  • the free end of the enlarged section 142 has weakened zones allowing a variation of the section of this end and more precisely a centripetal deformation of this end.
  • the weakened areas consist of notches 150 regularly distributed at the outer end of the section along the contour thereof. These notches delimit tabs 152.
  • the section 140 is generally of constant section. It comprises at its periphery, at the right of the tongues 152 when the two sections are nested, a peripheral bead consisting of a metal ferrule 154 attached by welding on the wall of the section 140.
  • This ferrule has in section a generally cylindrical connection zone 156 extended by a cylindrical bearing surface 158 disposed away from the wall of the section 140.
  • the bearing surface 158 is connected to the bonding surface 156 by a front generally frustoconical retainer 160.
  • the bearing surface 158 At its free end, the bearing surface 158 has a folded edge 162 directed towards the wall 140 and kept away from it. So, the support range 158 generally cylindrical is connected to the wall of the section 140 only by one side and extends cantilevered along this wall.
  • An interval 164 is delimited between the wall 140 and the bearing surface 158.
  • the ferrule 154 forming the bead is bonded to the wall of the section 140 by a weld 166 formed at the end of the bonding strip 156. This weld is formed on the opposite side to the interlocking side of the two sections 138, 140.
  • the tongues 152 are deformed radially outwards and are connected to the running portion of the widened section 142 by a frustoconical section 170 delimiting a shoulder for the support of a toroidal seal 172 received. between this frustoconical section and the folded edge 162.
  • each tongue has an inward necking, which delimits an inclined surface 176 adapted to rest on the frustoconical retention front 160.
  • This inclined surface 176 is extended by a raised edge 178.
  • the surfaces 176 , 178 delimit between them a channel of revolution generally in V.
  • the device For holding the two assembled sections, the device comprises a strapping 190 comprising a clamping band 192 and not shown means of traction of this band.
  • the clamping band has a main flat surface 194 bearing on the main surface of the tabs 152.
  • the band 192 On its side edge, the band 192 has a peripheral shrinkage 196 having a shape adapted to engage in the necking 174 of each of the tabs .
  • the necking 196 generally has a V-shaped section proper to be applied to the tabs 176 and 178 of the tabs and thus maintain the necking end of the tabs bearing on the frustoconical surface 160 of the bead 154.
  • the presence of the bead 154 forming a front 160 retaining the necking end of the tongues, conjugated to the particular shape of the strapping band ensuring a maintenance of the necking of the tabs behind the front 160 guarantees satisfactory performance of the assembly.
  • the presence of a seal 172 interposed between the shoulder defined by the frustoconical surface 176 and the bead 154 provides a satisfactory seal.
