A driving unit has a crown (4), a catch follower (42) and a cylindrical cam (5) to automatically drive a cylindrically-shaped end fitting (2) in direct and indirect manner by axially pivoting along a portion of a turn during a phase where the end fitting passes from the separated position to the retightened position. The unit is provided in an assembly intercalated between the end fitting and the pliers.</p> |
