description A retainer means for the connection between a drill bit and a chuck fastening of a rotating tool, in particular for a rock drill arrangement, whereby the chuck fastening comprises first retainer means, and the drill bit comprises a drill head and a shaft that comprises second retainer means and third retainer means, whereby a connection between the chuck fastening and the drill bit can be switched between a condition that allows disengagement and a locked condition. Driving of the tool leads to the connection between the chuck fastening and the drill bit being set into the locked condition, in which locked condition disengagement of the chuck and the bit is prevented through the first retainer means being brought into interaction with the third retainer means by an axial disengagement displacement of the drill bit.
