Cargo containers used on shipboard and also for rail and truck transport are provided at each of eight corners with hollow corner blocks each having a vertical opening (either top or bottom, depending on location of the block at top or bottom) and two outward-facing side openings. Each side opening is oval, having a horizontal minor and a vertical major dimension. The shore at at least one end has a fitting formed of an oval inner member which is dimensioned to fit into a side opening, an outer member which is at least as large as the inner member and a connector between these members having a diameter less than the minor dimension, and a length equal to the wall thickness of the block. Thus, the inner member may be inserted through the side opening so that the connector is in the opening. When the fitting is turned 90 DEG , the fitting is affixed to the block. A tongue may be associated with the fitting to extend through the side hole and prevent the fitting from twisting and working out of place. The fitting may be internally threaded and used with an oppositely threaded, similarly shaped fitting which engages the block of an adjacent container. A double-ended, oppositely threaded screw is threaded into both fittings and may be tightened to hold the containers in position. Alternatively, each fitting may be connected by a swivel to a turnbuckle which is attached at its opposite end to a fitting, an arrangement useful when the containers are somewhat out of alignment. A pear-shaped ring may also be formed on the fitting to receive the eye of a cable lashed to a deck or other support.
