ABSTRACT:
A Conversion ring is provided for externally flanged mouths of tanks having two distinct locking means, one serving to prevent any axial displacement of the ring in relation to the filler mouth and the other for preventing any rotation of the ring once the latter is placed on the mouth. Both locking means cooperate with the external flange. The conversion ring provides security both as regards the sealing of the tank and as an anti-theft device.
