A sealing assembly designed to co-operate with a screw provided with a tightening slot by being mounted therein in such a manner that once said assembly is sealed the tightening slot is hidden in a manner that is not reversible except by destroying the seal, and further comprising a breakable drive suitable when the sealing assembly is subjected to a tightening action, for driving the screw in a tightening direction inside a receptacle provided for this purpose and for breaking once the screw becomes blocked, so as to prevent any loosening action being applied via the breakable drive. |
