A holding device for machine tool inserts includes a recess delimited by clamping jaws. The recess serves as a clamping seat for the insert. The holding device also includes a slot extending the recess and having a receptacle for a spreading body of a spreader key. The slot has a half-circular expansion on one of its edges serving as a receptacle for the spreading body. The cross section of the spreading body of the spreader key is a polygon outline in the shape of an isosceles triangle whose corners are each rounded with an equal radius of curvature.
