Abstract: Disclosed is a closing plug is provided for closing through-openings in components, such as components of motor vehicles. The closing plug includes a base body made from a hard component with a closing wall for covering a through-opening, and a sealing/fastening device made from a soft component. The soft component is configured to be sealed and connected to a wall of a carrier component that bounds a through-opening. The closing plug can be inserted into a through-opening in an assembly direction that extends orthogonally to a wall of a carrier component that bounds a through-opening.

Abstract: A seat belt guide device for a passenger restraint belt of a motor vehicle is provided, wherein the seat belt guide device includes a fastening device with at least one spring-actuated catching device, with which the seat belt guide device can be snap-fitted or fastened to a motor vehicle in an assembly direction, wherein the seat belt guide device is preferably molded from at least one plastic injection.

Abstract: A bolt fastener includes a plurality of fixing structures that are arranged radially around a receiving space for a bolt and are axially pivotable, wherein the fixing structures have, in the direction of an axial receiving space for a fastening bolt, engagement faces for engagement with a bolt and have, at diametrically opposite ends, bearing faces with which the fixing structures are supported counter to an outward movement, wherein bearing structures for the bearing faces are also provided, which cooperate in a supporting manner with the bearing faces, wherein the bearing face and bearing structure are dimensioned such that they disengage when the fixing structures are pivoted counter to the insertion direction of the bolt, wherein the radial spacing between the bearing structures and a bolt mounted in the receiving space is smaller than the entire extent of the fixing structures.
