Abstract

A device for coupling two containers comprises a pair of connecting sleeves, each having closing flaps that can be moved from a closed position to an open position by a part-turn actuator, with the outer surfaces of each closing flap facing away from the container lying flush with the outer surface of the relevant connecting sleeve in the closed position and the closing flaps are each seated in an essentially circular seal. To prevent the accidental opening of the closing flaps, each of the connecting sleeves is provided with a radially-movable pin in the wall adjacent the seal, which pin can be pushed radially inward to produce a bulge in the seal which will hold the respective closing flap in its closed position and which pin can be radially moved outward to release the flap.
