A front jaw having a housing receiving a release spring therein, through which housing extends a pull rod acting onto two toggle levers. In order to improve the release operation in such a front jaw, the invention provides that the housing has two bearing surfaces designated for a bearing part, which bearing surfaces are vertically spaced from the pull rod, and that the axles of the two toggle levers are arranged in the bearing part which rests in the skiing position under the influence of the release spring on the two bearing surfaces.
