Perfected label which can be attached to a commercial article to emit an alarm signal, and relative device for detaching the label from the article whereto it is attached

A security label for attaching to an article, the security label comprising:

• a label body having a first housing with a first engaging portion;
• and
• a first band for attachment of the article to said label body, said first band having securing teeth projecting from a first longitudinal surface, and second and third engaging portions longitudinally separated from each other and that engage said first engaging portion,
• said first band further having an end section that is engaged both by said first housing and by an intermediate section of said first band when said end section and said intermediate section are compressively opposed to each other within said first housing,
• said securing teeth on said end and said intermediate sections of said first band being mutually engaged by compressive contact within said first housing so as to block relative movement of said end and said intermediate sections of said first band within said first housing in a disengagement direction to preclude loosening of said first band from the article.

A cutting device for removing a security label having a label body, and a band for attachment of the article to the label body, and means for restraining relative movement between the band and the label body, the means for restraining comprising, on the label body, a housing suitable for being entered by an end section of the band which is engaged both by the housing and by an intermediate section of the band to define an engaging section, the end section and the intermediate section being compressively opposed to each other within the housing, the hand having securing toothing projecting from a longitudinal surface, the securing toothing on the end and the intermediate sections of the band being mutually engaged by compressive contact within the housing so as to block relative movement of the end and the intermediate sections of the band within the housing in a disengagement direction to preclude disengagement of the band from the article to be secured, the cutting device comprising:

• a support base for the label body;
• and
• cutting means extending perpendicularly to a surface of said support base,
• said cutting means being designed and adapted so as to cut the engaging section of the band.
