A coupling bolt includes a connecting portion with which the coupling bolt is fastenable to or in a first component, and a shaft extending from the connecting portion and defining a longitudinal axis of the coupling bolt. The shaft has a pre-fixation portion and a fastening portion, and along the longitudinal axis in the direction of the connecting portion the pre-fixation portion comprises a first head portion with a first diameter, a subsequent first, tapering transition portion and a first locking portion with a second diameter which is smaller than the first diameter. Along the longitudinal axis in the direction of the connecting portion, the fastening portion includes a second transition portion adjacent to the first locking portion, a subsequent second head portion with a third diameter that is larger than the first diameter, a third tapering transition portion and a second locking portion.

A coupling seat provides a seat space in which the coupling head of a coupling bolt can be releasably locked and moved linearly in the seat space. The seat has a wall that surrounds the seat space, and the dome has a locking structure to fasten the coupling seat in an installation opening in a component. The seat has an open end and a closed end with a locking structure for the head of the coupling bolt. The locking structure of the dome comprises latching bars that are arranged opposite each other on an inner wall of the seat space and parallel to a longitudinal axis of an inner dome cross-section and form an undercut opposite the insertion direction. The locking structure permits movement of a coupling bolt along the latching bars in the seat space transverse to the insertion direction.

Plug-in coupling with tolerance compensation

A connection unit for connecting a first component to a second component with a distance in between. The connection unit has a connection screw having a head in the shape of a first ball segment and a shank. The shank has an outer thread. The connection unit also has a base element having: a second outer thread, and a first portion having a first inner diameter; a through-opening is provided at a second axial end and has a second inner diameter which is smaller than the first inner diameter, and an outer side of the base element is in the shape of a second ball segment. The first portion and the through-opening are distanced axially and are connected by a transition portion, which at least partly provides a bearing surface for the head of the connection screw, and the shank extends through the through-opening.

A coupling bolt or pin, in particular a ball pin, with a coupling head, such as a ball head, and a thread shaft. The thread shaft comprises a thread in a longitudinal portion of the thread shaft, which extends parallel to a central longitudinal axis of the thread shaft. Within the longitudinal portion of the thread a thread inhibition is provided by means of which a frictional connection between the thread and a counter thread engaging therein and being present at a radial inner wall of a thread opening is increasable. A disc-shaped support structure is provided between the coupling pin and the thread, a radial extension of which is adaptable to a diameter of the thread opening so that the coupling pin is supportable against a lateral load with respect to the axis of the coupling pin within the thread opening.

An arrangement for fastening first and second components with automatic compensation in spacing between the components has a base element with first and second axial ends and a holding structure for holding the base element in an opening of the first component. An adjusting unit screwable into the base element has a driver unit. A fastening screw is connectable to the adjusting unit via the driver unit, such that, when the fastening screw is rotated, the adjusting unit can be rotated conjointly and moved into contact with the second component. The holding structure has a holding segment arranged such that, by the holding segment, an angle between the first and second component can be compensated such that, when the adjusting unit makes contact with the second component, a longitudinal axis of the fastening arrangement runs perpendicular to a plane of the second component.

A blind rivet for establishing a screw connection between a support component and a fastening part has an elastic outer body and a metal bushing arranged therein. The outer body is at least partially surrounded by a fixing sleeve which fixes the outer body on an end portion in the metal bushing.

A retaining clamp of a quick release fastening device, which is latchable in a component opening and in which a fastening bolt is lockable, comprising the following features: two spring legs arranged opposite to each other in a V-shape, the arrangement of which comprises a tapered open end at which the V-shaped spring legs are not connected to each other, and the arrangement of which comprises a widened end, at which the V-shaped arranged spring legs are connected to each other via a connection web with a central passage opening, and each of the two spring legs arranged in a V-shape comprises a central window with a spring web arranged therein, which is fastened at one side and is at least once angled in its course in the direction of the widened end.

An extension adapter of a plug-in coupling, with which a free space between a male coupling element and a female coupling element can be bridged in a connecting manner and which comprises the following features: a male coupling end which can be inserted into the female coupling element, a female coupling end in which the male coupling element can be received and which is connected to the male coupling end via an intermediate piece, and a locking element which is displaceably arranged in the axial direction of the extension adapter and with which, in a locking position surrounding the female coupling end, the release of a male coupling element from the female coupling end is prevented.

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.
