A quick connector with a compressive and rotational locking and unlocking mechanism includes a socket, a plug, a rotatable collar and an undulant resilient piece. The socket includes a first connector body and a plug-connection trackway extending obliquely and having an engaging notch at a terminal end thereof. The plug includes a second connector body and a first limiting wall protruding from the plug. The rotatable collar can be assembled on the plug and includes an engaging protrusion and a second limiting wall. When the rotatable collar is rotated, the engaging protrusion enters into the plug-connection trackway and moves to the terminal end of the plug-connection trackway, and the undulant resilient piece abuts against and forces the first and second limiting walls away from each other, such that the engaging protrusion is lodged in the engaging notch to form a locked state.

A system and method including a fastener clip assembly including a cap configured to be secured to a chassis through a chassis slot and a pin configured to be secured to a body panel, wherein the pin is configured to be secured to the cap. The pin includes a pin head having a bottom surface and the cap includes one or more fingers. The fingers are configured to bend outward from an original position based at least in part on the pin being inserted into the cap and are configured to bend back to the original position based at least in part on the pin head moving past the fingers. The fingers are configured to secure the pin to cap based at least in part on the fingers engaging a bottom surface of the pin head. The cap includes one or more limiters corresponding to the one or more fingers. The limiters are located to the outside of the fingers, and the limiters are configured to prevent breaking of the fingers based at least in part on the limiters limiting an outward bending of the fingers.

A pull buckle, which includes a lock body, a fastener, a first elastic member and a key assembly. The lock body is provided with a mounting cavity and an insertion port. One end of the fastener is provided with a connecting portion, which is inserted in the mounting cavity. The first elastic member is defined on a bottom wall of the mounting cavity and the bottom wall faces to the insertion port; the first elastic member contacts with the connecting portion when the fastener is inserted in the mounting cavity. The key assembly is clamped to the connecting portion so as to lock the fastener in the mounting cavity; or the key assembly is pressed to unlock the connecting portion, the first elastic member ejects the connecting portion out of the mounting cavity and releases the fastener.

A retention ring is configured to retain components within a transmission assembly. The retention ring has an annular main body defining an opening through a center thereof. The annular main body defines an outer curved surface and an inner curved surface, the annular main body having a distal face disposed in a distal plane and a proximal face disposed in a proximal plane. A first set of retention features extend from the inner curved surface, and a second set of retention features from the outer curved surface. One of the sets of retention features is configured to engage a backing plate or an outer member, and at least one of the sets of retention features is entirely disposed between the proximal plane and the distal plane. A transmission assembly includes the retention ring and an adjacent external snap ring.

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.

A plug-in connector has two pushbuttons arranged laterally thereon. An annular, asymmetric spiral spring is inserted in such a manner that the spiral spring, in its locking orientation, permits the respective pushbutton pin to move into the plug-in connector housing and prevents the pushbutton pin from moving out of the plug-in connector housing. The spiral spring can tilt from its locking orientation into its release orientation when arranged with its inner region in a release groove of the pushbutton pin. In its release orientation, the spiral spring permits the pushbutton pin to move out of the plug-in connector housing. This permits actuation similar to a ballpoint pen with only a few components and with high operating comfort.

A push-on fastener includes a base, a first radial barb, an axial support, a second radial barb, and a protrusion. The base defines an opening. The first radial barb extends from the base. The axial support extends from the base. The second radial barb extends from the axial support. The protrusion extends from the axial support.

A coupling element of a two-part plug-in coupling has a head section from which a female connection structure extends perpendicularly in an installation direction of the coupling element, with a locking web projecting inwards on an inner side so that a male bolt element can be inserted into the connection structure opposite to the installation direction and can be locked there, or a male cylinder-like connection structure extends so that the male cylinder-like connection structure can be inserted in a female receiving element and can be locked there. The coupling element has an integral locking structure which has a circumferential, or a plurality of locking webs which, together with the head section, form an installation gap for receiving the component, so that the female or the male coupling element can be locked in the opening of the component with a relative movement in installation direction between coupling part and component.

A self-fastening device for joining two objects together. The fastening device has a main slot for receiving an anchor from a second object and at least one branching slot for accommodating a latch, which by spring, magnet or gravity force is biased to the engaged position. When the anchor is inserted into the fastening device it is locked inside securely, fastening the two objects together. When a magnet strong enough to overcome the biasing force is brought from outside of the object into the vicinity of the latch, it moves the latch away from the engaged position, thereby unlocking the anchor and unfastening the objects.

Unique securement devices, usable for example as tripod feet, each feature a bistable spring band encapsulated in an outer skin with a set of optionally magnetic embedments discretely spaced along the band, and a coupler at one end for attachment to a tripod leg or other component. Unique ball and socket joints employ both a snap fit and a secondary retention mechanism to reliably secure together various components, including said securement devices and tripod legs. One joint includes an externally convex and internally concave ball coupler for optional mating with either a larger socket coupler or smaller ball. One joint includes a stabilization sleeve for angularly locking the ball and socket joint. An elongated support, usable as a tripod leg for example, features threaded connection ports usable to either directly mount threaded third-party componentry, or to receive a threaded ball coupler by which socket-equipped componentry can be indirectly attached.
