The first retention element includes a retention surface and a lower surface (23). The second retention element (8) engages the lower surface (23), as the male portion (5) is received in the female portion (4) in the upward direction, and resiliently deforms so that the second retention element (8) locates over the first retention element and abuts against the retention surface.

A fastening apparatus includes an annular base element having an assembly wall for abutting a first component and a first fastening wall for abutting the second component, and an assembly element having a bottom wall. To enable passage through a second through-opening of the second component, the assembly element has a smaller diameter than the base element. At least two diametrically opposed foldable retaining arms are arranged radially circumferentially and connect the assembly wall to the assembly element. The retaining arms are each connected to the assembly element and the base element via a respective joint and form an articulated joint in the region between the joints. A region of the retaining arms between the articulated joints and the assembly wall forms a fastening portion, and at least one catching device is provided to connect the base element to the assembly element in an assembly position.

A fluid container for releasable connection to a vehicle component, wherein the fluid container has at least one fastening lug with an opening which is aligned with a plug-through opening in the vehicle component and the connection is secured by a locking pin which can be extended into the plug-through opening and the opening and/or opening and can be locked in an end position by a rectilinear plug-in movement in a plug-in direction; in order to increase the load-bearing capacity of the connection and to simplify the installation, it is proposed that the fastening lug has a locking device which is arranged in alignment with the respective opening and the locking device includes at least two elastically resilient tabs which act in a latching manner on a thickened locking portion of the locking pin and thereby secure the locking pin in its axial direction.

A coupling for connecting a circuit board to a mount with a fastener. The mount may be connected to a component. The fastener includes a first snap-fit connection formation for establishing a snap-fit connection with a second snap-fit connection formation provided on the mount. When connected, the fastener clamps the circuit board against the mount. The fastener further includes a first engagement formation configured to engage with a second engagement formation on the mount for bracing the snap-fit connection.

In some examples, an apparatus can include a base plate to interface with a printing device, where the base plate includes an extension member having a pawl, and a lock ring, where the lock ring includes a blocking key, where the lock ring is to interface with the base plate such that the blocking key prevents rotation of the extension member to lock the base plate to the printing device.

An apparatus for connecting a first component to a second component by a ball which is fastened to the first component and which is fastenable in an opening of the second component includes a tool which includes two gripping elements and a retainer. The ball can be encompassed and pulled into the opening in a fastening direction by the two gripping elements. The second component is holdable in a position relative to the tool along the fastening direction by the retainer. The two gripping elements are movable relative to the retainer along the fastening direction to pull the ball into the opening until the first and second components are in contact with one another. The tool is movable in three dimensions by a robot.

In order to provide a method for producing a plastics component by means of which a plastics component having at least one fastening portion for fastening at least one fastening element is producible simply, it is proposed that the method should include producing a base body of the plastics component and at least one fastening portion of the base body in a single method step by means of a moulding tool, wherein the fastening portion includes at least one receiving opening into which a fastening element is introducible in a direction of introduction, for the purpose of fixing it to the fastening portion, wherein the fastening portion includes at least one undercut portion which adjoins the receiving opening in the direction of introduction and to which the fastening element is fixable with positive engagement for the purpose of fixing it in opposition to the direction of introduction.

A fastening system comprising a second fastener fastened to a first fastener; the first fastener comprising a hollow housing having a side-wall and a top-wall; a first aperture formed in the side-wall and in the top-wall of the hollow housing, the first aperture configured for entry of the second fastener during fastening of the second fastener and first fastener; a second aperture formed in the side-wall of the hollow housing; a beam formed in the side-wall between the first aperture and the second aperture, the beam attached at opposing ends to the side-wall; the beam blocks the first aperture to inhibit separation of the second fastener from the first fastener through the first aperture; and the beam is configured to be deformed during fastening of the second fastener to the first fastener.

A coupling for connecting a circuit board to a mount with a fastener. The mount may be connected to a component. The fastener includes a first snap-fit connection formation for establishing a snap-fit connection with a second snap-fit connection formation provided on the mount. When connected, the fastener clamps the circuit board against the mount. The fastener further includes a first engagement formation configured to engage with a second engagement formation on the mount for bracing the snap-fit connection.

A snap-in socket panel with a night lamp includes a first panel, a second panel, a resilient sheet bracket arranged vertically to the flat portion, and a resilient sheet connected to the resilient sheet bracket by a plug-in structure. The plug-in structure includes a slot provided on the resilient sheet bracket and an insertion block provided on the resilient sheet. The opening direction of the slot is set towards the first panel. During assembly, the insertion block on the resilient sheet is inserted into the slot on the resilient sheet bracket from bottom to top, to connect the resilient sheet and the resilient sheet bracket, and then connect the second panel to the first panel. The second panel can block the opening of the slot, thereby preventing the resilient sheet from falling out. The socket panel has fewer components, a simple structure, and faster, more convenient assembly.
