The embracing-holding body 3 comprises first and second holding members 5 and 6 for openably-closably pivoting mutual ones, a cylinder lock 7 and a dead bolt 8. The lock 7 is fixed to the holding member 5, and locks the holding members 5 and 6 in a closing position. The holding members 5 and 6 enclose the nut 107 and the flange ring 2 by a holding recessed part 621 in the closing position. The dead bolt 8 locks by engaging with an engaging recessed part 611b in the closing position of the holding members 5 and 6. The dead bolt 8 releases a lock by separating from the engaging recessed part 611b when unlocking the cylinder lock 7 by key operation.
