Abstract

Abstract A locking jalousie frame having a pair of longitudinally extending, spaced, substantially parallel side rails provided with fixed pivots supporting jalousie retaining cover assemblies. Each of the cover assemblies includes a sheath provided with a socket arranged for retainingly receiving an end of a slat. A filler member is insertable into and removable from the sheath independently of the slat for permitting installation and removal of the slat in an opposed pair of the sheaths, while removal of the filler member, and accordingly the slat, from the sheath can only be accomplished from the normally interior side of the jalousie so as to prevent surreptitious illegal entry through the jalousie.
