• a first part arranged at said second shaft end of said bolt shaft, said first part being connected to said bolt shaft and said breakable integrity element via a coaxially arranged shank, said first part having a first thread cooperating with said threaded bore;
• a second part arranged between said first part and said second shaft end of said bolt shaft, said second part having a second thread cooperating with said threaded bore;
• and
• first entrainment means arranged between said first and second parts in such a way that:
• upon rotation of said bolt shaft and said first part in a tightening direction, said second part is entrained in said tightening direction, and
• upon rotation of said bolt shaft and said first part in a loosening direction, opposite to said tightening direction, said second part remains stationary.
