There is disclosed a tool for extracting an anti-tamper ring (24) from a valve assembly (16). The tool has four claws (50) spaced about the anti-tamper ring and each claw has leading and trailing claw tips (54, 56). An actuating mechanism moveably supports the claws for movement from a first position through a third position. In the first position the claws are adapted to have at least one claw tip resting on the anti-tamper ring. In the second position the claws are adapted to have the claw tips moved readily inwards towards the axis of the valve assembly and vertically upward relative to the first position so as to engage and lift the anti-tamper ring from the valve assembly. In the third position, the claws have the claw tips moved radially outward relative to the second position to release the anti-tamper ring from the claws. |
