Bead reinforcement with tubular structure with divisible armature

Radial anchoring device for at least one end of a flexible tubular structure by abutting a flange after passage through a bore made in a rigid mating flange, said flexible tubular structure having at least at one end thereof a bead reinforced by a rigid armature, said rigid armature having predivision zones formed therein, said anchoring device being characterized in that said armature, being one-piece and rigid at the time it is embedded in the bead during manufacture of said tubular structure, is mechanically divisible into predefined segments by flexing two consecutive segments up to breakage in a predivision zone, said division being accomplished at the time of mounting of the flexible tubular structure, in order to offer the bead the possibility of being folded and allowing it to slide into the bore of the rigid mating flange without its radial rigidity being affected, through a pinching effect exerted on the divided segments by the tensioning of the flexible tubular structure under the internal pressure of use, thereby enabling a mounting of various types of mating flanges at the time of delivery rather than during a manufacturing of the flexible tubular structure.
