Abstract
A device for the closure and sealing of envelopes and the like. First and second elongated strips of plastic material are foldable upon each other along a narrow longitudinal hinge line. The first strip has a series of locking pins distributed along its length. Each of the locking pins has a weakened base. The second strip is provided with a series of sockets adapted for receiving respective locking pins in locking relation therein. To permit the device to be opened easily when it has been applied to a plastic envelope 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 is weakened starting from a first end, and each strip is provided, at its first end, with an appendage capable of being held between the fingers of the user.
