Abstract:
A kit for rigidly connecting two containers (6) provided at their corners with hollow corner fittings (4), wherein the corner fittings are provided with slots (14) through which their interior is accessible from the exterior of the container, comprising:a spacer portion (20; 40; 120; 172; 186) for abutment on the outer surfaces of corner fittings of two containers to be connected and facing to each other which spacer portion, when the containers (6) are rigidly connected together, ensures a predetermined spacing between them; two hammer portions (18; 42; 118) either of which can be introduced into the interior of a respective one of the corner fittings of two containers to be connected and facing to each other, said hammer portions being formed as to overlap with the corresponding inside walls of the corner fittings; screwthreaded engaging means by which the hammer portions can be moved towards each other thereby pressing the outside of the corner fittings against the spacer portion, wherein said screwthreaded engaging means is provided by a screwthreaded rod (16; 116) which has at its end regions screwheads adapted to be screwed into respective screwthreaded holes of the hammer portions (18; 42; 118) which screwthreaded rod passes, with said components adapted to be assembled for rigidly connecting the containers, through the spacer portion and is rotatable from outside the spacer portion and upon rotation moves towards each other the hammer portions which have been introduced into the interior of the corner fittings (4) through slots (14) formed in their side faces; and a tightening sleeve (24; 138) non-rotatably connected to the screwthreaded rod (16; 116), wherein the screwthreaded rod and the tightening sleeve in an assembled state are arranged within the spacer portion (20; 40; 120) and are rotationally driven from outside the spacer portion by means of a tool, wherein said spacer portion (120) is provided with an opening (159) for insertion of a locking screw (160) to prevent the tightening sleeve (138) from rotating.
