End-fitting for flexible pipe

A fixing end-fitting for a flexible tubular pipe, comprising at least, from the inside outward, an internal sealing sheath (2) made of a plastic, generally a polymer, a pressure vault formed by a short-pitch helical winding (3) of a metal profile wire, an intermediate sheath (5), at least one tensile armor ply (6) wound with a long pitch and at least one external protective sealing sheath (7), the end-fitting including a stepped part (112) that can slide in a stepped cylindrical housing of the end-fitting (11) and is designed to ensure, through two deformable crimping elements (113, 116), that the internal sheath (2) is fixed and sealed at the front and that the intermediate sheath (5) is fixed and sealed at the rear, bolts (120) allowing the stepped part (112) to be brought up to the end-fitting (11) and fixed thereto, characterized in that the stepped part (112) and the deformable elements (113, 116) form three separate elements.
