Abstract
A closure device, preferably made of plastic, serves for closing bags. It consists of a male section (1) and a female (2, 5 and 6), which are respectively joined to film (3 and 4) and may be detachably connected together. In order to ensure that such a closure device may be readily closed while at the same time being simple and cheap to produce, at least two spaced continuous projections (8) are provided on the side of the film (3) opposite to the male section (1). Similar projections (9) may advantageously be placed on the opposite side of the female section.
