A stopping fixture for a hollow spindle of a headstock has two elements movable relative to one another in an axial direction of the spindle and insertable into the latter, whereas the elements have inclined surfaces so that when one of the elements is axially displaced relative to the other element, at least one element moves radially outwardly relative to the other element and thereby the elements are firmly clamped against the inner wall of the spindle.
