An electrode fixing sleeve is provided, an object of which is to create an electrode fixing sleeve, which, when used in a system with an electrode lead, does not damage the electrode lead even when a very strong substantially radial force is exerted onto the electrode fixing sleeve. In accordance with at least this object, an inner lateral surface of the electrode fixing sleeve is provided at least in part with an adhesion-enhancing surface structure. Since the adhesion-enhancing surface structure has adhesion-enhancing properties, this provides the advantage that the electrode fixing sleeve can be secured without exerting a strong radial force onto an electrode lead.
