The buckle for safety belts in vehicles provided with a pretensioner engaging said buckle is provided with a compensating mass which at the end of the pretensioning travel prevents a mass-inertia-induced movement of the release button in the actuating direction. The compensating mass is formed by a lever which is pivotally mounted on the housing and which comprises a gear element which is in permanent meshing engagement with a rack on the release button. On each actuation of the release button the lever is pivoted, the easy mobility thereof thereby being ensured even after a longer period of use of the buckle.
