ABSTRACT:
A locking device for double sliding doors or windows consisting of at least two separable and superposed plates to be located between the adjacent vertical jambs of the exterior and interior doors. The plates have a shank and two oppositely directed tongues at each end of the shank. The plates are thin enough to be separately introduced edgewise between the adjacent jambs and rotated flatwise one over the other. The space between the tongues is determined to abut against the adjacent jambs. All the plates are fastened together to prevent them from being rotated edgewise and removed from between the jambs.
