Muzzle for bottles of champagne, sparkling wines and the like, characterized by integrating a wire frame, single piece, which determines an arc constituted by a double step of the wire itself, twisted, capable of enclosing and retaining the head of the plug in a substantially diametrical plane, establishing two opposite columns that reach up to the neck of the neck of the bottle, and comprising this arc a free end in which the two wire passages form a loop, while at its other end its steps branch in the opposite direction and in the opposite direction. A plane orthogonal to that of the arch, to establish a closed contour that crosses the loop, capable of adapting in the shoulder of the projection, and forming the circular contour symmetrically with respect to the arch, and a trapezoidal expansion that is subjected to torsion to determine the total application of the outline on the projection.
