A portable alarm device comprised of an electronic circuit that, among other components, includes a power cell, a cell clip that holds the cell in position and an audio output means for emitting an audible alarm sound. The circuit is mounted in a folder with a centralized fold, thus forming two folder halves positioned in spaced apart adjacency, the folder including an interlocking means for temporarily securing the folder halves together so that the folder remains in a closed position. A tab is positioned on one folder half opposite the circuit and is designed to easily slide between the power cell and the cell clip when the folder is in the closed position, thus breaking the circuit and preventing the alarm from sounding. When the folder is placed in the closed, but not secured orientation, between or under an object of importance, the alarm will sound if the object is moved since this allows the folder halves to move apart thus withdrawing the tab and closing the circuit.
