A method for producing a holding element on an edge region of a molded body made of a brittle material. The molded body is placed in a form tool that forms a charge cavity in the edge region of the molded body. The charge cavity is at least partially filled with a plastic material, and the molded body having the holding element formed thereon is then removed from the form tool. According to this invention, in order to optimize the production process, the molded body is held in the form tool by a clamping element. A section of the charge cavity is defined by the clamping element. A sealing element is applied to the molded body in a transition region between the charge cavity and the clamping element. The plastic material is introduced into the charge cavity by extrusion.
