Thank you!
This chunk of code works:

...
self.window.connect("delete-event", self.hide_subwindow_cb)
....

def hide_subwindow_cb(self, widget, event):
         # redefine 'delete-event'.
         # Hide window instead of it destroying
         widget.emit_stop_by_name('delete-event')
         widget.hide()
         return True
