A fastener includes a head configured to be anchored to a part, and a locking member extending from the head to a distal end. The locking member has at least one protrusion spaced from the head, and a tool engaging head at the distal end. In use, the locking member extends through an opening of a panel such that the head is retained on a first side of the panel, the distal end is disposed on a second side of the panel, and the at least one protrusion abuts the second side of the panel to secure the panel to the fastener. The fastener includes a resiliently deformable portion arranged such that rotation of the tool engaging head deforms the resiliently deformable portion and moves the at least one protrusion out of abutment with the second side of the panel to release the panel from the fastener.

A fastener assembly for releasable interconnecting two objects comprises a retainer having means at the top end for attaching the retainer to a first object and an end wall at the bottom end having an aperture. A post affixed to a second object at its bottom end is captured within a central cavity of the retainer by resilient snap fit wherein either the post or the retainer is radially deflectable. A locking element slidably connected to the retainer is axially moveable between locked and unlocked positions operative to restrict the relative radial movement of the post and the retainer to prevent the removal of the post. The locking element maybe a pin moved by a magnet and extendable into a bore of the post by a spring. Alternatively, the locking element may be a sleeve closely fitted around the outside of the retainer.

A tether clip includes a clip body including a panel anchor part and a trim anchor portion connected to the panel anchor part. The clip body has a moving space therein and a trim trigger in the trim anchor portion to be deformable in the moving space direction. The tether clip has a head anchor part with a head hook thereon, a tether connecting the clip body and the head anchor part, and a coupling pin. The coupling pin is inserted into the moving space and includes an inclined slope configured to contact the trim trigger and move the coupling pin toward the panel anchor portion when the trim trigger is deformed inside.

An artificial muscle includes an electrode pair including a first electrode and a second electrode. One or both of the first electrode and the second electrode includes a central opening. The first electrode and the second electrode each include two or more fan portions and two or more bridge portions. Each fan portion includes a first end having an inner length, a second end having an outer length, a first side edge extending from the second end, and a second side edge extending from the second end. The outer length is greater than the inner length. Each bridge portion interconnecting adjacent fan portions at the first end.

A batten fixing clip, comprising: a male connector comprising a batten interface portion for attachment to a batten, and a female connector interface portion for engaging a female connector; and a female connector comprising a support structure interface portion for attaching to a support structure and a male connector interface portion for engaging the male connector, the male connector interface portion including a retainer and a resilient clip comprising of an aperture, wherein the aperture receives at least part of the female connector interface portion and the clip biases the female connector interface portion against the retainer when in use.

The apparatus for fastening a vehicle component in and/or on a vehicle has a sound insulation element with a carrier layer and a sound absorbing layer. An anchoring recess is formed in the carrier layer and has an insertion opening in a first side of the carrier layer, which insertion opening is adjoined by a receiving space which is delimited by the plastic material of the carrier layer and is defined by a closed circumferential inner side and a closed bottom surface. An anchoring element is further provided. The anchoring recess has a constriction area formed on the circumferential inner side and at least partially narrowing the receiving space, with a widened widening area adjoining in the direction of the bottom surface. The anchoring element has an anchoring shoulder for engaging behind the constriction area when the anchoring element is received by the anchoring recess.

A pipe press-fit connecting apparatus includes a connecting device. The connecting device may be used to connect a connected unit to a pressing power providing unit. The connecting device includes a fastener and a coupling pin. The fastener is installed at one end of the installation hole on an exterior surface of a cylinder block and has a fastening pin configured to be resiliently arranged and at least partially be exposed to the installation hole. The coupling pin is inserted through the installation hole and the insertion hole through another end of the installation hole on the exterior surface of the cylinder block to be resiliently coupled to the fastening pin to couple the connected unit to the pressing power providing unit.
