Claim:
A safety device for a piece of luggage, comprising: a first outside zipper ( 1 ) comprising a plurality of first teeth ( 1 a ); and a second inside zipper ( 2 ) comprising a plurality of second teeth ( 2 a ), wherein the outside and inside zippers ( 1 , 2 ) are superposed in an immediate proximity of one another, such that the first and second teeth ( 1 a , 2 a ) of the outside and inside zippers ( 1 , 2 ), respectively, touch under an action of an external pressure on the outside zipper ( 1 ) using a tip or a pointed tool (P) in such a way that, when the external pressure is exerted by the tip or the pointed tool (P) on the outside zipper ( 1 ), the first teeth ( 1 a ) are caused to come into contact with the second teeth ( 2 a ) and to rest on the inside zipper ( 2 ) to withstand against penetration of the tip or the pointed tool (P) and to prevent the first teeth from dislocating downward under the external pressure of the tip or the pointed tool (P).
