A latch for maintaining in a closed condition doors hung by hinges on posts alongside access openings to containers such as packing cases and the like, and more especially of the kind with catches on the ends of upright rods mounted on the fronts of the doors remote from the hinges for axial rotation by operating handles affixed to the rods for engagement of the catches in and disengagement of the catches from keepers fixed to the cabinet casing in positions to be above and below the rods when the doors are closed, is characterized in that each keeper has two wedge-shaped projections whose tapered ends are adjacent and define between them a seating, and one of which has a double flange extending to the entry to said seating and providing a head, and each catch comprises a stem from which extend laterally two opposed pairs of projections shaped to define a wedge-shaped space between the two projections of each pair, each keeper and the catch associated therewith being so co-ordinated that when the latch is operatively mounted on a container having doors and the stem of the catch occupies the seating in the keeper, the two wedged-shaped projections of the keeper occupy substantially completely the spaces between the pairs of catch projections, and the catch projections of one pair are positively engaged below the head forming part of one of the keeper projections.
