ABSTRACT:
A security device for preventing unauthorized separation of a door from a cooperating buck assembly, in which first and second plate members are respectively carried by the door and the buck assembly and cooperate with each other to prevent movement of the door in a lateral direction when the door is closed. The first plate member is of unique configuration and is arranged to interlock with adjoining structure on the second plate member to keep the door from moving in its plane. In certain embodiments a Z-shaped support element separate from the plate members is mounted on the buck assembly in juxtaposition with the second plate member, and in some cases either the first plate member or the second plate member includes a pivotally supported cam element which moves into cooperating relationship with the other member as the door reaches its fully closed position.
