ABSTRACT The invention relates to a closing device for flexible containers made from tube-or bag-shaped semi-finished products for the transporting and storing of free-flowing or pourable goods, comprising a clamping device of several rods which can be fixed in position in relation to one another. Known closing devices have the disadvantage that they consist of a relatively large number of individual parts, which makes the handling difficult and increases the susceptibility to trouble. So as to make available an im- proved closing device the invention proposes that the clamping device comprises a winding rod or wrapping bar provided with a slot, wherein the upper part and the lower part of the container can be pushed into the slot and, by turning these parts over at least two times around the edges of the wrapping bar formed by the slot, can be wound on tightly and without folds by at least 270°, and wherein the wrapping bar is prevented from unwinding by at least one other rod or unwrapping preventing means. The latter may be formed by a sleeve which can be pushed onto the wrapping bar and engages firmly around the wound-on container opening, said sleeve when pushed on being fixed in position in such a manner that it cannot turn in relation to the wrapping bar. This ensures a quick and reliable fixing-of-position of the container opening which has been wound onto the wrapping bar.
