<p>Coupling (1) for connecting of pipe shaped sections comprising a first pipe section (2) and a coupling device (6) arranged to connect the first pipe section (2) with a second pipe section. When joined together, the first pipe section (2) is arranged to receive the second pipe section in such a way that the first pipe section (2) and the second pipe section forms an overlapping region. The wall (3) of the first pipe section (2) is provided with a through hole (8) in the overlapping region (7) and the coupling device (6) is adapted to protrude through the hole (8). The coupling device (6) is at least at one of its ends (9 or 10) slidably attached in such a way that a rotational displacement around, and essentially perpendicular to, the axial direction of the pipe section (2) will give rise to a change between a first position for locking, wherein said coupling device (6) is protruding on the inner side (4) of the first pipe section, and a second position for release wherein the coupling device (6) essentially not is protruding.</p> |
