The locking device includes a pressure sleeve that is spring-loaded via an assigned spring element, and a stop sleeve, the stop sleeve having a contact surface on its inner circumference, and the spring-loaded pressure sleeve pressing the at least one locking element in a locking position against the contact surface. The tubular tool holder has at least one recess in which the at least one locking element in the locking position is located, at least portionally, the at least one recess having a ramp-type guideway. The at least one locking element is displaceable along the ramp-type guideway from the locking position to an unlocking position.
