<p>The device (1) has two complementary closure assemblies (10, 20) defining a main direction, where the closure assemblies have respective complementary profiles extending parallel to a longitudinal axis (X). A slider (30) includes two side walls, and a central wall defining non-parallel channels for receiving at top closure assemblies (12, 22), so as to urge the top closure assemblies to open and close depending on the direction of movement of the cursor. The complementary profiles include serrations (24) extending in a direction perpendicular to the longitudinal axis.</p> |
