摘要： The invention relates to a method for producing a holding element (10) on an edge region of a moulded body (30) consisting of a brittle material. Said moulded body (30) is placed in a form tool by which means a charge cavity is formed in the edge region of the moulded body (30). Said charge cavity is at least partially filled with a plastic material, and the moulded body provided with the holding element (10) formed thereon is then removed from the form tool. According to the invention, in order to optimise the production process, the moulded body is held in the form tool by means of a clamping element (40.3); a section of the charge cavity is defined by means of said clamping element (40.3); a sealing element (20) is applied to the moulded body, in the transition region between the charge cavity and the clamping element (40.3); and the plastic material is introduced into the charge cavity by extrusion.
