An installation tool for a two-stage clip is described. The tool includes a base element and a plunger element. The base element can include a plunger installation cavity and a clip receiving cavity. At least a portion of the plunger element can be retainably engaged in base element. The plunger element can be movable within the base element between a retracted position and an extended position. In the extended position, a portion of the plunger element can extend into the clip receiving cavity.

A trim panel mounting system is provided for securing a trim panel to a substrate. That trim panel mounting system includes a push pin, a push pin holder and a trim panel. That trim panel includes at least one mounting post engaging the push pin holder and a resilient retention finger capturing the push pin between the trim panel and the push pin holder.

A tether has a pair of guide plates. The pair of guide plates has two sides. A distance between points located on the two sides increases, as the points on the two sides approach a tip of the tether. The tether may have elastic branches. The pair of guide plates may have protrusions protruding toward an anchor. The tether may be made long by curving a tether intermediate portion. The tether may have a second guide plate and a third guide plate. When a pillar garnish is moved in a direction away from a pillar, the two sides of the guide plates are brought into contact with a rim portion of a tether housing portion defining the tether inserting aperture, thereby preventing the tether from rotating about a center axis line of the clip and the anchor to pass through the tether inserting aperture. When a bottom wall of the tether housing portion comes to a tether portion located between the guide plates and the anchor, the elastic branches and the protrusions prevent rotation of the tether. The second and third guide plates also prevent rotation of the tether.

A system and method including a fastener clip, the fastener clip including a first piece made of an elastic first material. The first piece includes a pair of legs joined at a head portion, and one or more pairs of barbs coupled to the pair of legs. The barbs are configured to dig into the blade and to secure the fastener clip to the blade at least based upon the fastener clip being placed over the blade. The fastener clip includes a second piece made of a softer second material. The second piece includes inside and outside portions to the outside and to the inside of the first piece. The outside portions are configured to engage a slot in a chassis.

A system and method including a a fastener clip assembly including a tub configured to engage and be secured to a slot in a chassis. The tub is configured to be secured to the slot bases at least upon the tub comprising two or more tabs. The tabs are attached to the tub along a top portion of each of the tabs, and each of the tabs are configured to bend along the top portion of the tabs. Each of the tabs are configured to bend in response to the tub being inserted into the slot and to bend back to original positions of each of the tabs. Bottom portions of each the tabs secure the tub to the slot.

A spring clip includes a first frangible feature extending between a first cantilever bar and a support post and a second frangible feature extending between a second cantilever bar and the support post. The frangible features provide a readily perceived indication of proper spring clip installation.
