Compensation element for joining components

A compensation element for joining components made of fusible plastics, which is at least in sections formed as a conically shaped hollow body, said hollow body being configured axi-symmetrically in relation to its center axis and having an inner surface, said inner surface running parallel to its center axis, and an outer surface, said outer surface lying at a specific angle in relation to said center axis, comprising at least one heating element which, when supplied with energy, heats at least some regions of the inner surface or the outer surface of said compensation element or of both surfaces to produce a welded joint with said components,

• wherein, starting from each outer edge of said hollow body, cuts are formed therein, wherein at least a portion of said cuts extend close to or beyond a pre-defined flexibility securing plane of said compensation element, and wherein at least a first cut starting from a first outer edge substantially in an axial direction, the cut extending continuously from the inner surface to the outer surface of said compensation element, and at least a second cut starting from a second outer edge substantially in an axial direction, the cut extending continuously from the inner surface to the outer surface of said compensation element, are provided, both cuts extending to or beyond the flexibility securing plane,
• wherein said flexibility securing plane contains as an intersection with the compensation element a complete circle or a complete ellipse, the surface normal thereof lying parallel to said center axis of said hollow body or at an angle thereto such that a closed circumferential ring is produced nowhere in said body,
• wherein said compensation element comprises fusible plastics.
