Abstract
A twist-proof mechanical connecting assembly includes first and second components. The first component has a recess formed therein with a groove in the form of at least one pocket. A connecting element in the form of a bolt penetrates the first component and is secured to the second component for interconnecting the components. The bolt has a polygonal head including a safety cup embedded in the recess. At least part of the safety cup is outwardly bent into the at least one pocket for locking the safety cup to the first component and securing the connecting element against loosening.
