Closure for bags and the like, essentially characterized by consisting of a plate provided with rounded corners defining an elementary and flattened box, held by its ends by means of respective flanges facing the body of the bag, ensuring the fixing by means of a plate of its same shape located in the back face, through which the aforementioned eyelashes protrude, being bent at right angles in facing arrangement, with rigid fastening of the plate, which, in its central part, comprises a hollow part in the form of a body of revolution and a bulb structure, obtained by shaping a metal sheet and forming on the inside face of the plate a flange based on bent terminal appendages in the form of opposite arms that allows, in addition to the secure fastening of the element its axial rotation, while the other end of the hollow part forms a transverse expansion capable of receiving and retaining the facing ends of an element annular interlocking and locking functions of the device.
