Abstract:
    The invention is to provide a burglarproof tag which cannot be stripped from a commodity without sounding an alarm by inserting a thin plate between the tag and the commodity to retain an operation rod of a burglar detection switch with respect to the burglarproof tag fixed to the commodity. This tag is provided with an enclosure 1, a burglar detection switch 5, a hole 1b opened in the bottom of the enclosure, and an operation rod 5b of the burglar detection switch 5, and the enclosure 1 is fixed to a commodity 11 with the operation rod 5b pressed in; and when the enclosure is separated from the commodity, the operation rod projects to turn on or off the burglar detection switch, thus detecting burglary. In this case, a front end face 5c of the operation rod 5b is made orthogonal to an axis a, and a front end part 5d is formed so as to have a concave surface.
