Abstract

A connecting part of a ball joint between leg prosthesis components with a flange intended to fasten to the one component, the flange having an adjusting element position on it, consisting of a cup and a four-sided pyramid positioned centrally upon its point. To improve the adjustability of the connecting part, the flange is a rectangular flange with four holes, upon which the adjusting element is eccentrically positioned.
