A fastening device for attaching an assembly comprising at least two planar elements, comprises: A clip for insertion into openings in the planar elements for holding the planar elements together including a planar head having a central opening for providing access to an inner cavity of the clip; two lateral upright members having a first end that is secured to the head and a second end, the second ends being joined to each other; and a pin that is intended to be inserted into an inner cavity in the clip in order to lock the assembly. The pin comprises at least one flexible bridging piece having a central portion that is connected to a main body of the pin by means of two flexible portions, and the pin contacts a lateral upright member of the clip to lock and hold the assembled planar elements together.

Expandable collet bodies with sectional finger-based anti-rotation features are disclosed. The collet body comprises not only a plurality of gripping finger as a first part of a two-part anti-rotation means (ARM), but also a first part of a two part translation arresting means (TAM), which may or may not be sectional in nature. The TAM prevents over translation of a collet body within the work piece(s), and cooperates with a second part of the TAM associated with a work piece or an auxiliary structure. In this manner, a collet body inserted into a work piece or auxiliary structure will not accidentally be pushed beyond the blind side of the work piece(s) during insertion or initial clamp-up.

A fastener assembly is provided. In one embodiment, the fastener assembly includes a panel fastener and a lock pin insertable into the panel fastener to a first position and a second position. The lock pin including a flexible arm configured to upon insertion of the lock pin into the panel fastener in a first direction to the first position, flex inwardly and then outwardly to bring an end surface of the flexible arm into engagement with a panel retention tab of the panel fastener. Upon insertion of the lock pin into the panel fastener in the first direction to the second position, the flexible arm is configured to flex inwardly to allow a retention tab to pass into the panel fastener to bring a retention surface of the lock pin into engagement with a first panel retention surface of the panel fastener.

A system and method including a fastener clip assembly including a cap, the cap including a cap top portion, one or more cap legs extending from the top portion, one or more feet at the bottom of the legs, and one or more tabs extending on the inside of the one or more legs. The fastener clip assembly also includes a pin, the pin being configured to slide around and within the cap, based at least upon the pin being configured to be snapped closed around the cap to form a cap-pin assembly. The cap-pin assembly is configured to couple a panel to a slot in a chassis based at least upon the cap-pin assembly being configured to attach to the slot in the chassis and to the panel. The cap is configured to expand around the chassis slot based at least upon the pin being configured to push the tabs outward in response to the pin being pushed up passed the tabs.

A clamp includes a lock and a key. The lock defines a first longitudinal axis, and the key defines a second longitudinal axis. The lock has a clamping body portion, a pair of opposing snap lock arms, and an annular shaped receptacle. Each snap lock arm has a mounting end integrally joined to the clamping body portion. Each snap lock arm is flexible about its mounting end. The annular shaped receptacle is defined by the pair of opposing snap lock arms, being disposed between the pair of opposing snap lock arms adjacent to the mounting ends. The key includes a wedge body portion and a deformable elastic annular head portion. The annular head portion releasably retains the key in the lock. The annular head portion is sized to engageably cooperate with the annular shaped receptacle to provide the releasable retention.

A fastener assembly includes a pin and a body. The pin includes a shaft that inserts into a central passage of the body. The body includes a flange and first and second arms that attach to a nose at a distal end. Each of the first and second arms includes an exterior flex point, an interior flex point, and a proximal end. The first arm is configured to move about a first proximal hinge portion. The second arm is configured to move about a second proximal hinge portion. A first brace extends from a first arm, a second brace extends from a second arm, and the first and second braces create an overlap area between the first arm and the second arm.

Embodiments described herein generally relate to an assembly for mating a retention clip to a bumper cover. The assembly includes a mating hole adapter including a body having a through hole of a first inner diameter. The assembly further includes a bumper cover including a through hole of a second inner diameter, where the first inner diameter of the through hole of the mating hole adapter is less than the second inner diameter of the through hole of the bumper cover. The assembly further includes a retention clip including a fastener having an outer diameter that is substantially equal to the first inner diameter, where the retention clip is mated with the bumper cover by the through hole of the mating hole adapter.

A fastening device for attaching an assembly comprising at least two planar elements, comprises: A clip for insertion into openings in the planar elements for holding the planar elements together including a planar head having a central opening for providing access to an inner cavity of the clip; two lateral upright members having a first end that is secured to the head and a second end, the second ends being joined to each other; and a pin that is intended to be inserted into an inner cavity in the clip in order to lock the assembly. The pin comprises at least one flexible bridging piece having a central portion that is connected to a main body of the pin by means of two flexible portions, and the pin contacts a lateral upright member of the clip to lock and hold the assembled planar elements together.

A fixing structure of a wiring member includes a plate-like member provided in a vehicle, a wiring member disposed on a main surface of the plate-like member, and a fixing member fixing the wiring member to the plate-like member. The fixing member includes a housing part inserted into the plate-like member, a locking protrusion provided to extend outward from the housing part, and a protrusion extension part housed in the housing part and spreading the locking protrusion outside to lock the locking protrusion inside the plate-like member.
