ABSTRACT:
A locking device for a set of double sliding doors comprising two U-shaped clips and a flexible band operatively engaging both clips. The locking device is designed to prevent the relative movement of double sliding doors which comprise an interior door and an exterior door, with the interior door sliding in an interior track and the exterior door sliding in an exterior track. The interior and exterior tracks are parallel to each other. In a closed position, an inside vertical stile of the interior door is adjacent to, and which overlaps an inside vertical stile of the exterior door defining a space between the interior and exterior doors. A U-shaped clip is secured to the inside stile of each sliding door. The flexible band is secured at its first end to the U-shaped clip secured to the inside stile of the interior door and then traverses through the space between the interior and exterior doors to the inside stile of the exterior door. At its second end, the flexible band is removably secured to the U-shaped clip secured to the inside stile of the exterior door. When the double sliding doors are in a closed position, they can be locked in a fixed position by securing the second end of the flexible band to the U-shaped clip secured to the inside stile of the exterior door. The double sliding doors are then unlocked by disengaging the second end of the flexible band from the U-shaped clip secured to the inside stile of the exterior door.
