A fixing of plugs by threading, characterized in that by carrying the bottle on its neck the characteristic spiral rib, the internal face of the side wall of the plug has a number of longitudinal notches of low depth (4) in a manner that the material raised or torn when practicing the slit or part of it is accumulated in the upper edge of this determining small projecting stops (5) under the precise circumstance that the length of the successive slits being regularly progressive from the edge of the stopper , the stops (5), together, form a fractional spiral whose passage coincides with that of the nerve of the neck of the bottle; for this purpose the stops (5) will be disposed somewhat inclined according to the direction of the turn they form. Accordingly, the fixing of the stopper is executed as usual in the screw plugs, the claimed stops (5) being located in contact with the lower part of the spiraling protruding rib of the neck of the bottle and pressed against it as much as the stopper has reached its limit of descent by resting its edge against the widening of the bottle.
