ABSTRACT:
An electric circuit, well concealed within a purse or satchel, comprises an alarm in series with a battery and a switch, said switch being kept open by a uniquely shaped prong inserted into a matching hole. Withdrawal of said prong results in closure of the switch and activation of the alarm. A switching means is recessed within the matching hole in such a manner that mere insertion therein or poking with a sharp-tipped object can not suffice to deactivate the alarm. A cord or wire attachable to both the prong and a part of the owner's body effects withdrawal of the prong, and hence triggering of the alarm, when the purse or satchel is pulled away from said body part, or vice versa, through an action of either a robber or of an owner in distress.
