Abstract

A device for the closure and sealing of envelopes and the like comprising first and second elongated strips of plastic material (2, 3), foldable, one upon the other, along a narrow longitudinal hinge line (4). The first strip (2) has a series of locking pins (6) distributed along its length, each of the locking pins having a weakened base, and the second strip (3) is provided with a series of sockets (8) adapted for receiving respective locking pins in locking relation therein. With the purpose of permitting the device to be opened easily, when applied to a plastic envelope (11) with the locking pins penetrating orifices formed along the two borders at the mouth of the envelope, at least a part along the length of the longitudinal hinge line (4), starting from a first end, is weakened (at 9), and each strip is provided, at its first end, with an appendage capable of being held between the fingers of the user.
