摘要： An end fitting (14) of a flexible pipe (14) for conveying a fluid that includes:



an end vault (42) and an outer cover (44) fixed around the end vault (42),
at least a front region (36) of an internal polymeric sheath (18),

at least end sections (40) of at least one tensile armor layer (24, 25) arranged around the internal polymeric sheath (18),


a front sealing assembly (54) arranged around the front region (36) of the internal polymeric sheath (18).




The front sealing assembly (54) includes a cannula (64) supporting at least one part of the front region (36) of the internal polymeric sheath (18) and an annular protrusion (66) arranged on an internal surface (48) of the end vault (42). The front region (36) of the internal polymeric sheath (18) is circumferentially tightened between the one protrusion (66) and the cannula (64).
