1. An apparatus comprising:a printed circuit board having a top surface, a bottom surface, and a hole extending through the printed circuit board from the top surface to the bottom surface; and
a hook clip at least partially disposed within the hole of the printed circuit board, the hook clip comprising:
a body having a looped structure and forming a hook gap, the body and the hook gap being in a plane;
prongs extending from the body, at least part of one of the prongs positioned out of the plane; and
retainers extending from the prongs, the retainers parallel to the plane;
wherein the retainers are repositionable between a rested state and a compressed state, where the retainers in the compressed state are positioned adjacent to each other such that the retainers overlap each other when viewed along a direction perpendicular to the plane and intersecting the retainers to enable the hook clip to be inserted into or removed from the hole of the printed circuit board.
