Abstract: A device for interlocking in elastic fashion two coaxial rotating pieces, respectively interior and exterior, having a cylindrical interface, comprises split pins which are introduced into seatings formed parallel to the rotation axis at the interface of the two pieces. The pins are hollow steel cylinders split in the longitudinal direction, each pin being free to rotate in its seating and containing a cylindrical shank threaded in the pin with a predetermined clearance to impose a limit value chosen having regard to the reduction of the width of the split of the pin under the effect of an excessive couple.
