<p>The invention relates to a visible device for guaranteeing that a first packaging has not been tampered with before first use. According to the invention, said device comprises a first vertical strap (1) having four arms, each having an oriented rack (3) on which a movable collar (2) is positioned horizontally at 90° and at a desired height, wherein said collar is provided, on the inside thereof, with a male (4) and female (6) non-return rack. When the collar (2) is concentrically tightened to the fullest extent thereof, the device (1, 2) is tensioned and simultaneously flattened against the primary package while irreversibly confining the latter, the deliberate destruction of the device being enabled by a detachable tab (7, 10).</p> |
