The suction teat fixing device is for use with a teat of rubber or similar material, and whose neck is stretched over a sleeve passed through a mouth plate. The outside of the sleeve (4, 5) opposite the mouth plate (13) forms an inclined supporting surface for a locking device (15, 16) fitting over the sleeve and movable on it. The device rests on the supporting surface after insertion of the sleeve in the teat. |
