ABSTRACT:
The invention is an improved device for securing doors against break-in, even when the door is unlocked. The invention consists of a hasp-like retainer member, an eye-type retainer member, and a bar-like security piece of rectangular cross-section. The retainer members are affixed to a wall or door casing on each side of the doorway of the door to be secured at approximately the mid-height of the door. The hasp-like retainer, which is hinge-like in operation, may be folded back against the wall or the door casing when not in use. When in use the hasp-like end is opened to a position generally perpendicular to the face of the wall of the casing. The bar-like security piece, being of a cross-sectional area that is slightly less than the opening in the hasp-like end of the retainer, and of a configuration that will fit into the hasp-like slot, is inserted into the hasp-like retainer member with the opposite end secured to the eye-type retainer member.
