An anti-shop-lifting device to be locked to a bottle-neck having an external circumferential bead, comprises an inner socket (10) to be passed onto the bottle-neck, and an outer socket (18) mounted externally on the inner socket and displaceable axially thereof. Retainers (21) are distributed circumferentially on the inner surface of the outer socket, which extend into the inner socket through openings (13) in the wall thereof to engage behind the bead. The retainers are substantially rigid but are flexible to yield, by engagement with the bead, at displacement of the device onto the bottle neck, to take a position behind the bead. Latch means (29) in a latching position lock the inner socket against displacement in relation to the outer socket in a position wherein the inner socket forms an abutment for the retainers preventing yielding thereof from the position behind the bead to prevent the anti-shop-lifting device from being removed from the bottle-neck |
