Abstract
A clamping device for fixing plastic molded parts during welding is proposed, comprising a flange-like fastening part for fastening on a plastics welding device, the fastening part having at least one first annular recess for receiving a clamping element and the fastening part having at least one second recess for receiving spring elements acting radially on the clamping element, the clamping element having at least one projection on an inner surface which is arranged opposite the outer surface of the plastic molded part. The clamping element allows good fixing of the plastic molded parts in a very confined space.
