A connecting apparatus is provided for connecting a number of components, in particular for connecting the enclosure parts of circuit breakers. The connection apparatus includes a connecting element which has a shaft, which passes through through-openings which are aligned with one another in the connection, having an insertion end and having a holding end opposite it. In order to achieve a turning or twisting distance which is as short as possible when the connecting element is twisted in order to brace the components while avoiding weakening of the material, the connecting element includes two fixing lugs at the insertion end. These lugs are bent in the form of a circular arc in an initial state and are bent out radially in the mounting state. Alternatively, two fixing lugs which extend like a fork in the shaft longitudinal direction in an initial state and which are bent out radially in the mounting state are provided at the insertion end of the connecting element.

Linking device for components, especially for housing parts of automatic cutouts

A connecting apparatus is provided for connecting a number of components, in particular for connecting the enclosure parts of circuit breakers. It includes a connecting element which has a shaft which passes through through-openings which are aligned with one another in the connection of the components, having an insertion end and having a holding end opposite it. In order to achieve firstly centering and secondly a turning or twisting distance which is as short as possible when the connecting element is twisted in order to brace the components, a first mounting depression, which holds the holding end and is aligned with the through-openings, as a centering cone, with the holding end being conical, forms a mating surface which corresponds with the centering cone.
