Abstract
A connecting expansion bolt over-molded with an expansion sleeve includes a bolt head at one bolt end and a bolt cone tapering in the direction of the bolt head. At the other bolt end, the bolt cone and an adjoining bolt shaft portion are over-molded with a plastic expansion sleeve, the sleeve end of which that surrounds the bolt cone is divided into a plurality of spreadable sleeve segments by open-ended slits. Provision is made for the sleeve end that surrounds the bolt cone to be divided into at least three sleeve segments. For at least two of the slits on the bolt cone that separate the sleeve segments from one another do not extend parallel to the bolt axis.
