A coupling device configured to couple first and second pipes, which comprises a first part coupled to the first pipe and which has a first contact surface, a second part coupled to the second pipe, separate from the first part, and which has a second contact surface configured to collaborate with the first contact surface, at least one clamp comprising at least one clamping jaw comprising a groove, configured to collaborate with the first and second parts, which has a cross section such that a concentric tightening of the clamp causes the first and second contact surfaces to be kept pressed against one another. Thus, the coupling device makes it possible to obtain a ball joint type connection between the first and second pipes.

A connection device for joining two pipe sections in a body of water has a first tubular body having a spherical face; a second tubular body having at least one spherical face; a tubular pusher arranged about the second tubular body and having a spherical face; a first mechanism for coupling the second tubular body between the first tubular body and the tubular pusher and providing a spherical coupling between the first and the second tubular body; and a second mechanism for blocking any movement about the spherical coupling of the second tubular body with respect to the first tubular body and the tubular pusher.

A ball joint includes a suspension house comprising an inner side, a house neck and upper flange, wherein a bearing ring, having a liner fastened to its inner surface, and an upper mating surface fastened to the corresponding mating surface on the lower side of the house; a suspension ball, complementary to the inner side of the house, comprising a ball neck and lower flange, the ball having a recess on the inside of the ball, the recess comprising an inner seal ring positioned on a bias ring in the recess; the seal ring providing a seal contacting the inside of the house and a piston seal contacting the inner surface of the recess wherein the bias ring biases the seal ring parallel to the axis of the neck and away from the bias ring.
