A closure device for packages having at least one self-adhesive closure element is disclosed. It comprises a self-adhesive glue layer (L<SUB>1</SUB>, L<SUB>2</SUB>) on the closure element, arranged for closing of the package. A release layer (F<SUB>1</SUB>, F<SUB>2</SUB>) covers the glue layer (L<SUB>1</SUB>, L<SUB>2</SUB>). At least one tear strip (G<SUB>1</SUB>, G<SUB>2</SUB>) is provided such that it can be torn through the package when the package is closed to form an opening. The tear strip (G<SUB>1</SUB>, G<SUB>2</SUB>) is provided on a part of the package forming the closure element, and on one side thereof that is facing inwards when the package is closed. Finally, the tear strip (G<SUB>1</SUB>, G<SUB>2</SUB>) is provided with a silicone layer on the side thereof facing the material of the package when the package is in a closed condition.
