A surveillance device in the form of an EAS tag (10) is provided, which includes a body (12) with one or more EAS markers (16) inside an inner cavity of the housing. The tag (10) further includes a detent (18) with one end (46) that is pivotally attached to the body (12) so that the detent (18) can pivot relative to the body (12) between an open condition and a locked condition and with a second end (52) that is releasably attachable to the body (12) when in the locked condition. When in the locked condition, the combination of the body (12) and a part of the detent (18) between its ends (46,52), encloses a space (20) adjacent the body (10) and an article such as an arm (32) of a spectacle frame can be gripped in the space. The tag (10) allows for tight gripping of various sizes of spectacle arms (32) by allowing the size of the space (20) to be adjusted. |
