Abstract
The present invention relates to a closing device for sachets comprising at least two complementary closing elements (200, 300) and an associated slider (100) comprising a central bead (140), adapted for modifying the joining state of said two elements (200, 300) so as to respectively separate or engage the latter according to its direction of motion, characterized in that the slider (100) comprises at least one flexible lip (145, 146) placed on the apex of the central bead (140) opposite a lead angle (216, 316) provided on the closing element (200, 300), according to a configuration such that any attempt to pull back the slider results in autolocking hanging of the lip (145, 146).
