Abstract: A coupling device for coupling containers includes a body part having a fastening piece and a cam part on upper and lower parts thereof, and a planar coupling plate between the upper and lower parts. The fastening piece is fastenable to an upper corner piece in a corner of a container by rotating the body part around its vertical axis. The cam part controls the motion of the body part and receives substantially vertical forces between the containers. The body part includes a first rotating locking part for preventing and/or releasing the motion of the body part, and a second rotating locking part for enabling and/or preventing lateral motion of the body part. The second locking part is in direct or indirect contact with the first locking part so that when the first locking part rotates, the second locking part also rotates, enabling a locking mode or an unlocking mode.

Abstract: The invention relates to a coupling device for coupling containers, particularly for coupling containers used in cargo ships and land transport, in which coupling device (1) there is formed in the upper part of its body part (13) a fastening piece (2), by which the body part is fastenable in a corner piece (26) in a corner of a container (40) by rotating the body part around its vertical shaft, whereby the fastening piece fastens in the corner piece (26) of the container, and that in the body part is formed between its upper part and lower part a planar coupling plate (3), and that in the body part there is a cam part (6) for controlling the motion of the body part and for receiving substantially vertical forces between the containers (40, 41), and that in the body part is fitted a first rotating lever-like locking part (8) for preventing and/or releasing the motion of the body part and, in the body part, there is a second rotating lever-like locking part (5) for enabling and/or preventing the lateral motion
