A tool assembly has a tool head insertable on a basic tool holder. The basic tool holder has a longitudinally displaceable locking bar and a plurality of slidable locking pins actuated by the locking bar. In a first position of the locking bar the locking pins are in an advanced position in which they project into respectively aligned lock holes of the tool head inserted on the basic tool holder. In a second position of the locking bar the locking pins are in a withdrawn condition, permitting the tool head to be pulled off the basic tool holder.
