Abstract: A connection end-piece of a flexible pipe includes an end vault extending along a central axis; an outer cover fixed to the end vault and defining, with the end vault, a reception chamber for receiving an end section of the armor elements of the flexible pipe; at least one annular member applied externally to the armor elements of the flexible pipe, the annular member being at least partially accommodated in the reception chamber between the armor elements and the outer cover. The annular member applies a radial tightening pressure higher than 100 bars onto the armor elements toward the central axis of the flexible pipe.
