A device for connecting two tubular pipe sections. A sealing device is arranged between the pipe sections. At their ends, the pipe sections in each case have a flange-type end piece. The pipe sections are held together by a spring device using a pre-tensioning force, the spring device having a mid-section extending at right angles to the longitudinal axis of the pipe sections. The spring device has a spring element, from whose transverse sides of the mid-section, which extend at right angles to the longitudinal axes of the pipe sections, spring limbs extend. Forming an at least approximate U-shape with the mid-section, the spring limbs extend at least partially over the periphery of the pipe sections, the spring limps each having a centrical cut-out that is adapted to the outside diameter of the pipe sections and in which a pipe section is accommodated in each case in the mounted state of the spring element.
