Fastening system for fastening a first component at a variable spacing on a second component

A fastening system for fastening a first component at a variable spacing on a second component, having:

• a main body,
• a slide, and
• an elongate locking element,
• wherein the main body has a mounting surface for mounting on the first component and a locating surface, through which an elongate depression recessed into the main body passes, for fastening to the second component,
• wherein the main body has a slideway to movably support the slide along the depression and the locating surface,
• wherein that side of the slide which faces the depression and that side of the depression which lies opposite the slide each have a first tooth system,
• wherein the locking element can be introduced into the elongate depression and has a second tooth system on two mutually opposite longitudinal sides and is designed to establish engagement between the first tooth system of the depression and of the locking element and between the slide and the locking element in a first alignment within the depression and to release it in a second alignment, and
• wherein the mounting surface and the locating surface are not parallel to one another.
