Indeed, having a protruding part 172 which extends rectilinearly over 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 maintaining 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 fixing is effected by means of assembly means.
  • assembly means can take different forms to allow the half-jaws of the first jaw 15 to come together.
  • the two half-jaws are assembled together by screwing.
  • the half-jaws are arranged to allow a screw to assemble the two half-jaws.
  • the two half-jaws are assembled together 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 able to deform to enter or leave the housing, the latter comprising a notch into which the notch fits.
  • the two of the two half-jaws are secured 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 fixing of a framework.
  • means for fixing a frame 30 are arranged These fixing means 30 on arranged on the upper face of at least one half-jaw 170.
  • These means 30 consist, for example, of a groove 31 which may be peripheral. or in two parallel portions arranged on the second jaw allowing the fixing of a U-shaped P-section. in fact, such a section consists of a metal or plastic or polymer sheet folded to have two parallel arms making it possible to obtain a U-shape 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 the fixing of said profile.
  • the means for fixing a frame 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 fit into the space between the two arms of a U or C section.
