ABSTRACT:
A frame assembly for doors, windows and the like includes a fastening element consisting of a longitudinal connecting portion and a transverse clamping portion, a first frame provided with a plurality of locking holes and a second frame provided with two fastening holes. The connecting portion has a side plate extending substantially perpendicular to either lateral side thereof and is provided with a plurality of threaded holes at an upper portion thereof for matching the locking holes. The clamping portion consists of a clamp plate punched and bent from a middle portion of the connecting portion and a grip plate in a relative clamping relationship with the clamp plate; the grip plate being provided with two projecting hook pieces for matching the fastening holes. The connecting portion may be inserted into the first frame so that they may be locked firmly and conveniently by screws. The clamping portion is fitted onto a rear side of the second frame such that the hook pieces of the grip plate hook against the fastening holes in the second frame to ensure the assembly.
