A pin retention device comprises a fastener defining a longitudinal axis, a first end and a second end along the longitudinal axis, a head at the first end and a threaded portion at the second end, a tubular spacer defining a thru-hole configured to receive the fastener, and a nut defining a threaded hold configured to mate with the threaded portion of the fastener.

A pivot structure includes a first pivot element, a second pivot element, and a fixing element. The first pivot element includes a through hole. The second pivot structure includes a pivoting portion. The pivoting portion is rotatably engaged with the through hole. The fixing element is coupled with the second pivot element. The fixing element includes a first retaining portion, and the first pivot element is retained between the second pivot element and the first retaining portion.

A wire-tray-assembly includes a wire-tray, a first-insert, and a second-insert. The wire-tray has a first-mounting-tab defining a first-aperture, and a second-mounting-tab defining a second-aperture. The first-insert is releasably retained by the first-mounting-tab and a first-mounting-stud extends through the first-aperture into the first-insert. The first-insert is rotatable about a longitudinal-axis of the first-mounting-stud. The first-insert defines a first-cavity into which are disposed first-pawls configured to releasably engage threads of the first-mounting-stud. The second-insert is releasably retained by the second-mounting-tab and a second-mounting-stud extends through the second-aperture into the second-insert. The second-body defines a second-cavity into which are disposed second-pawls configured to releasably engage threads of the second-mounting-stud. The first-pawls engage the threads of the first-mounting-stud and the second-pawls engage the threads of the second-mounting-stud when an installation-force is applied the first-insert and the second-insert along the longitudinal-axis of the first-mounting-stud and the second-mounting-stud.

A reciprocator-type quick-releasing mechanism includes a base, a latching component and an actuating component. The base has a first piercing hole and a first opening. The latching component is disposed on the base and includes a constraining portion and a resilient portion. The constraining portion is disposed inside the first piercing hole and connected to the resilient portion. The actuating is component disposed on the base and includes a pushing portion and an actuating portion. The pushing portion contacts the resilient portion to guide the resilient portion and connected to the actuating portion for aligning the first opening and a second opening on an external unit. The actuating portion is moved to slide the resilient portion, so as to move the constraining portion through the first piercing hole for letting the constraining portion leave a second piercing hole or pushing a buckling portion on the external unit.

A vehicle component fastener for fastening a first component to a second component of a vehicle, including a first part having a pin socket for receiving a head of a pin of the second component, and a second part having a fastening structure for fastening of the first component. The first part and the second part are connected to each other via a preassembly locking device in a preassembly position from which axial displacement into a final assembly position can occur. The preassembly locking device is releasable by introduction of the head of the ball pin or T pin into the pin socket such that the axial displacement into the final assembly position a) can be carried out with less effort than when the head of the ball pin or T pin is not introduced into the pin socket, or b) can be carried out at all.
