Hinged retainer assembly

1. An assembly comprising:

a clip portion including a first flexible flange and a second flexible flange that each at least partially define a central retainer passage and define a stud opening between the first and second flexible flanges;

a flexible hinge connecting the clip portion to a structure;

a tab located adjacent an opposite end of the clip portion from the flexible hinge; and

a lock portion located adjacent a second end of the central retainer passage opposite the flexible hinge located adjacent a first end of the central retainer passage, wherein the lock portion includes a ring having a central opening;

the first and second flexible flanges configured to expand outwardly to increase a diameter of the central retainer passage so as to allow a mounting stud to pass through the stud opening transversely as the assembly is being pivoted about the flexible hinge from a disengaged position into an engaged position.

2. The assembly of claim 1 , wherein the central retainer passage includes a contoured surface.

3. The assembly of claim 2 , wherein the contoured surface defines a threaded surface.

4. The assembly of claim 1 , wherein a first distal end of the first flexible flange and a second distal end of the second flexible flange each flair outward and away from the central retainer passage.

5. The assembly of claim 1 , wherein the central opening of the ring is at least partially aligned with the central retainer passage.

6. The assembly of claim 1 , wherein the ring includes a radially inner mounting stud contact surface.

7. The assembly of claim 1 , including a neck segment surrounding less than 50% of the central retainer passage and connecting the clip portion to the lock portion.

8. The assembly of claim 7 , wherein the neck segment surrounds less than 25% of the central retainer passage.

9. The assembly of claim 7 , wherein the neck segment flexibly connects the clip portion and the lock portion.

10. The assembly of claim 1 , wherein the clip, the flexible hinge, and the structure are a single piece unitary component.

11. The assembly of claim 10 , wherein the structure includes a flange having a stud opening.

12. The assembly of claim 11 , including a mounting stud extending through the stud opening and located in the central retainer passage and in engagement with the first flexible flange and the second flexible flange.

13. The assembly of claim 1 , wherein the stud opening extends throughout a length of the central retainer passage between the first and second flexible flanges.
