  • the two half-jaws 170 are assembled together before being coupled to the first jaw 15 and locked.
  • This first way is very practical in the case of half-jaws 170 provided with a hinge system 185. Indeed, in this first way, the half-jaws 170 are integral with each other before being coupled to the first jaw 15. This coupling is itself produced simultaneously with the locking of the two half-jaws 170 between them.
  • this second step is carried out so that the assembly of the half-jaws 170 into a second jaw 17, their locking and the coupling of this second jaw with the first jaw are simultaneous.

  • this second step consists in providing the two half-jaws 170. Then, the half-jaws 170 are manipulated to form the second jaw 17 by ensuring that the projecting parts of the half-jaws having a secondary complementary surface 192 can cooperate with the primary complementary surface 191.
  • the second step consists in assembling the two half-jaws 170 while inserting the first jaw 15 into the space E, of each half-jaw 170, between the inclined portion 174b extending orthogonally to the axis of the central portion and the surface of the half jaw 170.
  • the second step consists in assembling the two half-jaws 170 while inserting the relief 194 of the projecting part of each half-jaw 170 into the groove 193 arranged on the side wall of the first jaw 15.
  • the second step consists in assembling the two half-jaws 170 while inserting the first jaw 15 into the housing formed by the projecting part 1720, 1721 provided with the inclined surface and the surface of the half-jaw 170 from which this protruding part extends.
  • the membrane previously placed on the first jaw 15, is inserted between the primary complementary surface 191 of the first jaw and the secondary complementary surface 192 of the second jaw. This wedging of the membrane between the first jaw 15 and the second jaw 17 has the consequence of allowing said membrane to be fixed and maintained.
  • this configuration of the jaws 15, 17 makes it possible to maintain the membrane without causing a break in integrity.
  • the membrane is here wedged between the two jaws in that the complementary surfaces do not pierce said membrane.
  • the first jaw 15 and the second jaw 17 are such that they have a circular geometry.
  • This circular geometry applies primarily to the first jaw.
  • this circular geometry applies to the shape of the side wall 151 of the first jaw 15 on which the half-jaws 170 come to fit and to the area(s) forming the complementary surface.
  • the substantially circular shape of the side wall alone allows angular freedom for the assembly of the two jaws. Indeed, the circular shape allows the operator to install the two half-jaws 170 without constraint of angular position as visible at the figure 15 .

  • the upper part serves for the assembly of the two jaws then the upper part and/or the lower part are circular.
  • the groove 193 in which the relief 194 of the secondary complementary surface 192 is inserted extends over the periphery of the side wall 151', this side wall is circular.
  • the part In the case of a recess on the first jaw, if the part carries said groove then at least the upper part is circular. If the groove is arranged on the lower part then the upper part and the lower part are circular.
  • the half-jaws 170 are arranged so that the projecting part 172 of each half-jaw 170 matches the shape of the side wall forming the primary complementary surface. Indeed, having a protruding part 172 which extends straight across the width of the half-jaw 170 makes it possible to maintain the membrane M. However, if the side wall 151 forming the primary complementary surface is circular, then the protruding part does not provide optimal support.
  • the projecting part 172 is arranged to extend in a shape such that the secondary complementary surface and the primary complementary surface fit together perfectly. This variant advantageously makes it possible to have all of the secondary complementary surface which is useful for holding the membrane and for coupling the second jaw to the first jaw.
  • the first jaw 15 comprises two half-jaws. This variant is applied in the case of a jaw which is fixed to the central portion.
  • the two half-jaws are assembled to each other by screwing.
  • the half-jaws are arranged to allow a screw to assemble the two half-jaws.
  • the two half-jaws are assembled to each other by snap-fastening.
  • one of the half-jaws comprises at least one deformable blade provided with a notch while the other jaw comprises a housing.
  • the deformable blade is capable of deforming to enter or leave the housing, the latter comprising a notch into which the notch is inserted.
  • the two half-jaws are joined together by a hinge.
  • This hinge can be a strip of deformable material or a hinge and hinge system.
  • the two half-jaws 170 forming the second jaw 17 are arranged to allow the attachment of a frame.
  • means for fixing a framework 30 are arranged. These fixing means 30 are arranged on the upper face of at least one half-jaw 170.
  • These means 30 consist, for example, of a groove 31 which can be peripheral or in two parallel portions arranged on the second jaw allowing the attachment of a U-shaped P profile.
  • a profile consists of a metal or plastic or polymer sheet bent to have two parallel arms allowing a U-shape to be obtained or C depending on the orientation of said section.
  • the end of each arm of the profile has an extra thickness. This extra thickness is such that it can be inserted into the groove to allow said section to be fixed.
  • the means for fixing a framework comprise two parallel arms 33. These arms extend from the second jaw 17 in a direction parallel to the axis of the central portion. These arms have a spacing such that they can be inserted into the space present between the two arms of a U or C profile.
