Abstract:
A sealing assembly designed to co-operate with a screw provided with tightening means by being mounted thereon in such a manner that once said assembly is sealed said tightening means are hidden in a manner that is not reversible except by destroying the seal, said screw including a head and a shaft, said shaft being attached to and extending perpendicularly to said head, and further comprising breakable drive means, physically separate from said screw, 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 means, wherein said breakable drive means is suitable for cooperating with the tightening means of said screw and extends at least partially into a center portion of said head, said center portion of said head being above a center of said shaft.
