Abstract: An alarm tag made of two parts, one of which is provided with a pin (13) attached to the one part (12) to be located on one side of the product (11) with the pin extending through the product into locking engagement with the other part (10) located on the opposite side of the product. A resonance chamber (29), mounted in the one part (12), having a central outlet (30) is provided for activating the alarm device. A cover (19) is mounted on the one part (12) over the resonance chamber, and includes a central portion in register with the outlet (30), and bars (36) extending radially from the central portion (35) to the periphery of the cover, the bars defining slots (37) between adjacent bars.

Abstract: The invention relates to an anti-shop lifting device, intended to be passed onto and locked to a bottle-neck having an external circumferential bead. The device comprises an outer socket (15) which can be shifted in relation to an inner socket (10) between two end positions and is locked by latch means (24) in one end position. A number of retainers (21) distributed peripherally on the inner surface of the outer socket, when the outer socket is in said one end position extend into the inner socket through openings (13) in the wall of said inner socket to an engaged position in which the retainers engage behind the bead of the bottle-neck in order to prevent the anti-shop-lifting device form being withdrawn. The latch means (24) is biased to latching position but can be actuated by means of an external element (13) to a disengaged position against the bias in order to allow movement of the retainers from the engaged position and thus withdrawal of the anti-shop-lifting device from the bottle-neck.
