Abstract

A connecting device includes a connecting element arranged on a connectible part, which includes non-self-cutting retaining projections having a curved supporting surface in the shape of a circular arc in a longitudinal section that are insertable into a groove provided on another connectible part. The groove has a curved undercut surface in the shape of a circular arc in a longitudinal section, a base segment, and two undercut segments extending away from the base segment in a thickness direction. The retaining projections engage in the undercut segments of the groove, the connecting means guiding the parts in relation to each other. One connecting element includes a guiding groove with a slotted guide and the other connecting element includes a guiding element moveable along the guiding groove in a specified guiding path having varying distances from a contact surface of the part and/or abutment surface of the connecting element.
