A door hinge arrangement permitting opening of the door alternatively at either side, comprising a mounting for attachment to the door at the upper edge thereof, and a mounting for attachment to the door at the lower end thereof, each mounting carrying two hinge sets for engagement with hinge pivots fixed to the frame of the door, a trapping member associated with each mounting, the trapping member being slidable longitudinally of the mounting in either direction from a middle position and having a guide so constructed that in the initial phase of the opening of the door at one side each trapping member is so displaced as to trap the corresponding hinge pivot in the hinge seat at the other side of the door, the hinge seats being located at the outer ends of the mountings, the trapping members having a length not exceeding the distance between the outer ends of the hinge seats, a guide being arranged for displacing the trapping members in a direction away from the side, at which the door is being opened.
