Claims
- 1. A seal with anti-theft device for items having rod-like portions, comprising a hollow body suitable to contain an electronic signaling component and defining a contact surface for a rod-like portion, two parallel and mutually opposite guides protruding from said body, each guide having at least one saw-tooth engagement surface for the irreversible sliding, at right angles to the contact surface, of a slider which has complementary saw-tooth engagement surfaces, said rod-like portion being retained between said contact surface and a parallel contact surface defined by said slider, an annular gasket, in which said rod-like portion is to be inserted, being arranged between said saw-tooth engagement surfaces of said slider and being rigidly coupled to said slider by being monolithically provided with an annular tab surrounding a portion of said slider.
- 2. A seal with anti-theft device for items having rod-like portions, comprising a hollow body suitable to contain an electronic signaling component and defining a contact surface for a rod-like portion, two parallel and mutually opposite guides protruding from said body, each guide having at least one saw-tooth engagement surface for the irreversible sliding, at right angles to the contact surface, of a slider which has complementary saw-tooth engagement surfaces, said rod-like portion being retained between said contact surface and a parallel contact surface defined by said slider, wherein an annular gasket, in which said rod-like portion is to be inserted, is arranged between said saw-tooth engagement surfaces of said slider and is rigidly coupled thereto by being monolithically provided with an annular tab surrounding a portion thereof, said slider comprising wings which cantilever out and on which said complementary saw-tooth surfaces are defined at outward faces, said wings being flexible, said portion surrounded by said tab of said gasket being defined between said wings.
- 3. The seal according to claim 2, wherein said tab of said gasket is enclosed by a cover which is applied and rigidly coupled to said slider.
- 4. The seal according to claim 3, wherein said cover is provided with mutually opposite wings which define, as a whole, a surface for applying a label.
- 5. A seal with anti-theft device for items having rod-like portions, comprising a hollow body suitable to contain an electronic signaling component and defining a contact surface for a rod-like portion, two parallel and mutually opposite guides protruding from said body, each guide having at least one saw-tooth engagement surface for the irreversible sliding, at right angles to the contact surface, of a slider which has complementary saw-tooth engagement surfaces, said rod-like portion being retained between said contact surface and a parallel contact surface defined by said slider, wherein an annular gasket, in which said rod-like portion is to be inserted, is arranged between said saw-tooth engagement surfaces of said slider and is rigidly coupled thereto by being monolithically provided with an annular tab surrounding a portion thereof, said tab being arranged at right angles to said gasket.
- 6. The seal according to claim 1, wherein said gasket is made of elastomeric material.
