Abstract: A tolerance compensation arrangement for fastening first and second components with compensation of tolerances between the components. The arrangement comprises a base element having a first element with a first inner thread, a second element with a second inner thread, a supporting element arranged in between, and an adjustment unit with a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the sleeve. The outer thread forms a first thread pairing of a first thread direction with the first inner thread. A fastening screw, can be screwed into the second inner thread via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.

Abstract: To fasten a first component to a second component, a fastening clip has an integral, elongated structure with a first and a second fastening end. The first fastening end comprises an at least one-armed independent latching structure. The second fastening end is formed by a resilient clamp. The first and second latching structure act on an intermediate support structure. To connect the two components, the latching structure is latched in a component opening in a first component, and the second component is fastened between the support structure and a spring loop of the resilient clamp with the assistance of a cutout or a slot that is open on one side.
