A sealing arrangement for sealing the clearance between the outlet end of a rigidly mounted jet pipe and the inlet end of another pipe tiltable three-dimensionally with respect to the rigidly mounted pipe, one of the pipes being formed with a ball socket-like surface. A ring shaped seal support is mounted on the pipe not having the ball socket-like surface. A sealing ring in the support is formed of segments which overlap one another in the circumferential and axial directions, the sealing ring protruding from the support toward the ball socket-like surface. A corrugated flat spring is located between the sealing ring and the base of the seal support to urge the sealing ring toward the ball socket-like surface. The sealing ring is pressed against the ball socket-like surface and one wall of the support by pressure in the pipes when the engine is running, and that wall of the support is provided with pressure equalizing pockets.
