A bottle security device includes a housing with an electronic surveillance article tag therein and a ratchet strap which extends from the housing and loops around the bottle neck to secure the device thereto. The strap has one-way locking teeth which are lockably engaged by a locking mechanism in the housing when the strap is inserted therein to secure the strap in a locked position. The housing has first and second opposed outer surfaces which taper radially outwardly and toward one another in a manner which makes the housing difficult to grasp manually or otherwise, thus helping prevent the breakage and removal of the device from the bottle. The tapered outer surfaces also serve to deflect impact forces to the housing to help prevent unauthorized removal of the device. An arcuate channel of the housing receives and aligns the strap for improved locking capability.
