Abstract: A coupling piece for releasably connecting adjacent containers includes a housing, a rotatable locking bolt positioned within the housing, a rotatable actuating lever mounted in the housing and a spring device connected to the locking bolt for normally urging the locking bolt in a locking direction. The locking bolt has a crossbar located at each end thereof that is insertable into an opening in the adjacent containers. A portion of the actuating lever engages the locking bolt so that upon rotation of the actuating lever in a first direction, the locking bolt is rotated in a releasing directing which is opposite to the locking direction.

Abstract: A coupling piece for releasably connecting corner fittings of adjacent containers, especially of containers stacked on top of one another on board of ships. The coupling piece includes a single-piece housing, having a locking bolt which is rotatable to different positions by an actuating device being mounted in the housing in a longitudinally shiftable manner. The single-piece housing is provided with a passage, through which an appropriately formed cross-bar of the locking bolt can be pushed while being in an assembly position.
