A connection for conducting pressurized fluids between a tube and a connection component having a bore for receiving the tube. A clamping ring surrounds the tube and is seated on a seat between first and second bore segments and has an annular lip extending away from the seat. A locking bolt having a through-hole receiving the tube is threaded into the first bore segment and contacts the ring, an annular collar projecting from the locking bolt surrounding the lip and urging it radially inward to grip the tube when the bolt is tightened against the clamping ring. A sealing ring surrounding the tube is positioned between the clamping ring and a sealing ring seat defined between the second and third bore segments.
