A seal with anti-theft device for items having rod-like portions, particularly eyeglasses, 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 protrude from the 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. The rod-like portion is retained between the contact surface and a parallel contact surface defined by the slider. The seal is provided with an annular gasket, in which the rod-like portion is to be inserted, which is arranged between the saw-tooth engagement surfaces of the slider and is rigidly coupled thereto by being monolithically provided with an annular tab which surrounds a portion thereof.
