Abstract: A submarine connection for interconnecting a riser pipe and a flexible pipe (26). The riser pipe has an upper end and the flexible pipe (26) has a lower end (30). A connection assembly includes a rigid fitting having a first limb (64) to be connected to the lower end (30) and a second limb (66) with a connector (67) on the end, and a body (36) having a head (42) and an opposing base (46) provided with an end piece (52) to be mounted on the upper end. The connection assembly also includes first guiding elements (60, 86) secured to the body (36), extending in a position at a distance from the axis of the end piece (52), and second guiding elements (76, 81) secured to the first limb (64), suitable for cooperating with the first guiding elements (60, 86).
