End fitting of a flexible pipe, associated flexible pipe and related methods

An end fitting of a flexible pipe for conveying a fluid comprising:

• an end vault and an outer cover fixed around the end vault and delimiting a reception chamber,
• at least a front region of an internal polymeric sheath defining a central passage for conveying the fluid, the central passage extending according to a longitudinal direction,
• at least end sections of at least one tensile armor layer arranged around the internal polymeric sheath, the end sections being arranged in the reception chamber,
• a front sealing assembly arranged around the front region of the internal polymeric sheath,
• wherein the front sealing assembly comprises a cannula supporting at least one part of the front region of the internal polymeric sheath and at least one annular protrusion arranged on an internal surface of the end vault protruding toward the central passage, the at least one part of the front region of the internal polymeric sheath being circumferentially tightened between the at least one protrusion and the cannula,
• wherein the at least one protrusion is integral with the end vault and wherein the at least one protrusion is an annular ring.
