Connection end-piece of a flexible pipe for transporting fluid and associated method

A connection end-piece for connecting a flexible pipe for transporting fluid, the flexible pipe comprising at least one pressure sheath and at least one tensile armour layer disposed externally relative to the pressure sheath, the end-piece comprising:

• an end vault extending along a central axis;
• reinforcing armour elements of the at least one tensile armour layer, the reinforcing armour elements having an end section, the reinforcing armor elements wound with a long pitch and comprising wires or strips;
• an exterior cover fastened on to the end vault and delimiting with the end vault, a reception chamber for receiving the end section of reinforcing armour elements;
• and
• at least one annular member applied externally over the reinforcing armour elements, the annular member being accommodated at least partially in the reception chamber between the reinforcing armour elements and the exterior cover;
• wherein the annular member applies over the reinforcing armour elements a radial clamping pressure towards the central axis that is greater than 100 bars.
