Abstract
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.
