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

it is further of particular importance that, with suita

more permanent means of securing them to the frame,
namely by welding. Thus the former method of secur

edges and pressing this fold, with the interposition of a
cord, into t e assembly groove in the frame.

As a closure, a projection 10 is moulded onto one
