This security means is installed at the outer side of the panel in engagement with a securing device to prevent withdrawal of the securing device and the security means is secured from the inner side of the panel where an intruder would not have access so that the panel could only be released from the inside by an occupant of the premises, after which it could be removed from the outside.
