Abstract: A refrigerator has a body forming a compartment, and first and second doors mounted in side-by-side relationship on the body for closing the compartment. Each door is hinged along an outer vertical edge thereof such that the inner vertical edges of the doors face one another and form a gap when the doors are closed. In order to prevent cool air loss through that gap, a leak prevention member is hinged on the back side of the first door for rotation about a vertical axis. When the first door is closed, a pin on the leak prevention member engages a guide groove formed on the body for rotating the leak prevention member to an operative position in which it extends across the gap to resist cool air leakage. A locking element carried by the leak prevention member locks the leak prevention element against rotation to its operative position while the first door is open.
