The invention relates to a frame particularly for ladies’
handbags. In contrast to the metal frames with closing
means provided separately thereon, and particularly sol
dered thereto, hitherto commonly used for such purposes,
the frame of the present invention is produced with such
closing means and receiving means adapted to secure or 15
