Abstract: A theft alarm is provided for a hood ornament utilizing a pair of spaced plugs held apart by a coil spring and retained together by a central hook and threaded post which extend through axial bores through the plugs with the hook extending up through the hole in the hood to engage the hood ornament. The plugs each mount an electrical contact, and when the ornament is deflected, the coil spring is compressed between the plugs, bringing the electrical contacts into contact and setting off an alarm, which ordinarily is the vehicle's horn.
