ABSTRACT:
A coupling and arresting device for a double-sashed window is disclosed comprising a pin fastened to one sash and an elongated coupling piece fastened to the other sash, the pin having an enlarged head received with friction in a longitudinal slot in the coupling piece. A two-armed lever having a long arm and short arm is pivotally mounted in conjunction with the coupling piece so that a hook at the free end of the long arm blocks the slot in the coupling piece. By manipulating the short arm the hook may be raised to leave the slot unblocked.
