A rock-cutting tool is provided with an elastic component for securing in a bush of a tool socket. So that the force required for inserting the tool into the tool socket is relatively small and the force required for pulling the tool out is relatively large, the elastic component has projecting parts which in the tool socket assume a position from which they cannot be returned by an extraction force exerted on the cutting tool. An extraction force exerted on the tool causes the projecting parts of the elastic component to be at least partly sheared off or torn off the component area connected to the tool or causes the projecting parts to fold back, so that the tool can be pulled out of the tool socket. |
