Fastener

A fastener assembly comprising:

• a fastener comprising:
• a body portion extending along a longitudinal axis and defining a first end and a second end,
• a pair of tower legs extending from the body portion at the second end, each tower leg being resiliently deflectable relative to the longitudinal axis, and
• at least one mating feature positioned on an inward-facing surface of each tower leg and configured to engage a corresponding seating portion of a rib tower of the second component;
• a rib tower forming part of a second component, the rib tower including a seating portion configured to receive the mating features of the fastener;
• and
• a first component defining an opening configured to receive the fastener and engage the locking projections,
• wherein the fastener is configured to mechanically couple the first and second components together through engagement of the mating features with the rib tower and engagement of the locking projections with the first component.

A plastic fastener for coupling a first component and a second component, the plastic fastener comprising:

• a body portion extending along a longitudinal axis and defining a first end and a second end;
• a pair of tower legs extending from the body portion at the second end, each tower leg being resiliently deflectable relative to the longitudinal axis;
• and
• at least one mating feature positioned on an inward-facing surface of each tower leg and configured to engage a corresponding seating portion of a rib tower of the second component,
• wherein the mating feature is configured to facilitate insertion of the rib tower between the pair of tower legs and to resiliently engage the seating portion to mechanically retain the plastic fastener to the rib.
