• a second metal strip (1 18) can be inserted into the strap (100), for example by overmolding or by insertion into a cylindrical housing.
• the strap (100) is reinforced by one or more metallic inserts:
• the strap (100) may have a notched interior surface (1 10) (see FIG. 1 or 6), or a notched surface (1 15) see FIG. 7), or even a smooth surface, so as not to damage aluminum foil from bottle necks champagne, or bevelled with deformable protuberances (1 14) projecting from its interior surface (see Figure 1 1 or Figure 12).
• the smooth belt possibly having a continuous line of total or partial retention (1 19) in FIG. 17 has the effect of:
• the version described in FIG. 8 provides an additional tooth (121) on the inner surface (122) of the neck (120) .
• the serrated belt is thus locked simultaneously in two zones.
• the counterweight (310) consists of a plastic part molded for the toothing and of a metal part (330) constituting the housing of the spring (320).
• the spring (320) allows the counterweight (330) to be put under pressure on the teeth of the strap (100).
• the metal part (330) of the counterweight (320) under the action of the magnet of an unlocker will allow a displacement of the counterweight (320) in order to release the two teeth.
• a fixed tooth (121) has been molded in the body (122). This tooth (121) creates the second mechanical locking point.
• the toothing of the belt when it passes over the fixed tooth (121) will cause it to flex.
• the belt will return to position due to its shaping curve.
• the belt is locked at 2 points according to this embodiment.
• the shaping curve of the belt provides a spring effect. This spring effect will allow when the two locking points are released to return the strap (100) back.
• the secondary locking can be achieved by one or more teeth positioned on the part (220), according to a size specific to each tooth in order to offer other locking points to the belt (100).

• This telescopic plug is formed by a first tubular part (410) fixed to the housing (210) of the detection block (200).
• a second tubular part (420) whose outer section is smaller than the inner section of the tubular part (410) slides inside this tubular part (410) to allow an adjustment of the height of the telescopic plug (400).
• the second tubular part (420) is closed by a transverse disc, making it possible to protect the decorative aluminum envelope provided on certain bottles.
• Splines (41 1, 421) block the relative rotation of the two tubular parts (410, 420).
• This retractable telescopic cap (400) allows the height to be adjusted to any type of bottle, and in particular to take into account the height of the cap fitted to certain types of bottles.
• the two tubular parts (410, 420) are preferably transparent, made of a rigid plastic material, to preserve the visibility of the decorative envelope of the neck of the bottle.
• the strap (100) and the covers (410) and (420) may have suitable signage indicating where to limit the tightening of the belt on champagne bottles so as not to mark and damage the aluminum sheets covering the top of the champagne bottles by the flexible or fixed teeth of the belt,
• the two tubular parts (410, 420) have on the side of the connection with the housing (210) complementary vertical notches (415, 425), intended for blocking the movable cap at the precise height of the bottle neck to be protected introduced into the device. These notches (415, 425) are held together during tightening.
• the strap (100) has deformable protrusions (11-14) protruding from its inner surface allowing the pressure exerted on the decorative metal label surrounding the neck of the bottle to be adjusted.
• These deformable protrusions (1 14) have the shape of a tongue folded upwards, so that they define a conical crown flared downwards, allowing a progressive tightening of the strap around the neck of the bottle.
• This specific toothing of the belt makes it possible to adapt to different necks. In the event of a characterized vertical impact, the flexible toothing of the belt is altered to absorb the deformation due to the increase in the diameter of the bottle resulting from the impact. The teeth then return to their initial position when the thief tries to remove the device from the neck.
• the strap (100) is formed by plastic overmolding of an elastic metal blade, or by inserting a metal blade into a plastic part. It has notches on the outside extending between the free end (that is to say the one opposite the end extending the housing (210), and the lug (140). This free end can be engaged in the slot (130), where the locking device prevents the free end of the strap from being removed in the absence of unlocking.
• Security by ink flow is obtained by the addition of an ink bulb (500) housed in the housing (210) and intended to prevent and note the theft by breaking of the bulb (500) in the event of impact on the housing (210).
• a metal pin (510) is housed in a groove (520) of the housing (210) to ensure that the bulb (500) breaks in the event of an impact on the housing (210).
