A leaf seal for sealing a shaft rotating about an axis, in particular in a gas turbine, includes a plurality of spaced-apart leaves disposed in a concentric circle around the axis and fixed in position. Each of the leaves includes a surface oriented essentially parallel to the axis and an integrally formed element configured to position and retain the leaves in the leaf seal.
