In a door having a connecting link to a door frame of an improved locking mechanism on the closing edge of the door which includes a longitudinal engaging element movably mounted thereon. A corresponding longitudinal counter element is connected to the door frame; is generally parallel to and interlocked with the engaging element. The engaging element extends over at least a substantial part of the door height. Said engaging element is sufficiently movable so that it disengages the counter element so that the door may open relative to the frame. A blocking device is movably mounted on the door and in one position, retains the engaging element in locked position when the door is closed. A grip mechanism is movably mounted on the door and connected to the blocking means for moving it to a release position so that said engaging element can move to disengage said counter element. This same longitudinal engaging element and corresponding interlock counter element may be employed in connection with a door consisting of a pair of aligned leaves and wherein the engaging element of one leaf is adapted for movement relative to the counter element of the other leaf in such a manner as to disengage the respective elements permitting opening of the door leaves. The connection between the grip mechanism and the blocking device includes an elongated actuator which is pivotally mounted upon the door at one end and with its other end adapted to operatively engage the blocking device whereby inward pivotal movement of the actuator translates the blocking device to a "release" position. The grip means also include a door push as well as a door pull, both nested within openings in the door on its opposite sides, pivotally mounted upon the door.
