Abstract: Various embodiments relate to a tool-clamping system having two metallic shaft portions, wherein the first shaft portion has a locking pin at the end and the second shaft portion has a locking sleeve at the end, wherein, in order to establish a releasable drive connection, the first shaft portion can be introduced coaxially, by way of its locking pin, into the locking sleeve of the second shaft portion and the two shaft portions can be pivoted in relation to one another, in a locking pivoting movement, about a common geometrical longitudinal axis into a locking pivot position, wherein, over the course of the locking pivoting movement, at least one latching formation arranged on the circumference of the locking pin, snap-fits or snap-fit over at least one corresponding mating latching formation of the locking sleeve, the locking pin and/or locking sleeve being elastically deformed in the process.
