Abstract
The invention relates to a closure (3) that comprises two interacting pairs of locking ribs (23, 33) that function in pairs. Said locking ribs (23, 33) are formed integrally with connecting strips (17, 21) in which guide ribs (27, 37) are configured which engage in a common glider (31). The closure (3) is opened by conical grooves (29, 39) inside the glider (31) which modify the distance between the two guide ribs (27, 37) by pushing apart and separating or reuniting and joining them.
