| Zusammenfassung: | The invention concern a fixing end-fining for a flexible tubular pipe comprising an inner sealing sheath (
2
), a pressure vault consisting of a short-pitch helical winding (
3
) of a metal forming wire, an intermediate sheath (
5
) and at least a web of tensile long-pitch wound amour wire, (
6
) and an outer sealing sheath (
78
), the end-fitting comprising a staged part (
112
) capable of sliding into a staged cylindrical housing of the end-fitting and designed to ensure through two crimping elements (
113, 116
),the sealed fixing of the inner sheath and the intermediate sheath (
5
), screws (
120
) enabling the staged part (
112
) to be brought closer and to be fixed on the end-fitting. The invention is characterised in that staged part (
112
) and the deformable elements (
113, 116
) constitute three separate elements, thereby facilitating mounting and providing a better control of tightness |
