A locking pin arrangement with a basic element for receiving an insert and a fall-proof locking pin for fixing the insert in the basic element. The locking pin is at least partially inserted into a borehole of the basic element and is pushed towards an opening of the borehole by a spring. The locking pin has a guiding surface for axial guidance in the borehole, an outer thread and a constriction positioned between the outer thread and the guiding surface, wherein the diameter of the outer thread is smaller than the diameter of the guiding surface and the diameter of the locking pin at the constriction is smaller than the diameter of the outer thread. Further, the arrangement comprises an inner thread going from the wall of the borehole into the space formed by the constriction.
