Abstract: The invention relates to a self-locking and -releasing connector group, for the connection of two components, at least one of which comprises a hole for the partial introduction of the connector group and which is preferably a corner fitting on a sea freight container. Said group comprises a housing (2), at least one locking component (170), which can be displaced back and forth between a released position and a closed position, a stop component, displaceably mounted on the housing, whereby the housing may be fixed to one of the components and the locking component, in the released position thereof, may be inserted in the hole of the other component, during the relative manoeuvring of the components to be fixed together.

Abstract: A kit for rigidly connecting two containers provided at their corners with hollow corner fittings (4) has a spacer portion (120) which, when containers are rigidly connected together, ensures a predetermined spacing between them, a screwthreaded rod (116) provided at its end regions with screwthreads, and two hammer portions (118) which can be screwed onto respective ends of the screwthreaded rod and which can be introduced into the interior of the corner fittings through a slot (14) at the side surfaces of the corner fittings (4). In the condition of being assembled for rigidly connecting the containers, the screwthreaded rod (116) passes through the spacer portion (120), it is rotatable from outside the spacer portion and, upon rotation thereof, it moves the hammer portions (118) arranged in the corner fittings and engaging same towards each other, whereby the outsides of the corner fittings (4) are pressed against the spacer portion (120).
