They’re typically called plastic fasteners or clips — common terms include panel clips, body clips, trim clips, and push rivets. These small parts secure everything from exterior panels to interior trim and engine-bay liners.
What they do and where you’ll find them
Plastic clips come in many shapes and sizes. They keep panels aligned, seal gaps against wind and water, and prevent loose trim from rattling. You’ll encounter them on bumpers, fenders, door panels, dashboards, footwells, and under the hood. Over time they can become brittle or wear out, especially in harsh climates.
Common types of plastic clips
Categories you’ll encounter on modern cars
Below are the plastic fasteners you’re most likely to encounter on a modern car.
- Panel clips / body clips: generic retainers used to secure exterior body panels and molding.
- Trim clips: hold decorative or protective trim along doors, windows, and sills.
- Fender liner clips: attach the plastic liner behind the wheel well to the fender or inner structure.
- Bumper-retainer clips: secure bumper covers to the vehicle and align with other panels.
- Door panel clips: fasten interior door panels to the door structure.
- Christmas-tree (tree) fasteners: conical, barbed fasteners that expand in a hole for a tight grip.
- Push rivets: simple push-in fasteners that lock when inserted into a pre-drilled hole.
Choosing the right clip matters for fit, sealing, and noise control. An incorrect clip can cause gaps, water intrusion, or rattles, especially on exterior panels or trim pieces.
How to identify and replace plastic clips
When replacements are needed, start by identifying the original clip’s shape, size, and retention method. You can pull a sample from a spare panel or note its part number if available. Automotive parts retailers and salvage yards carry numerous clip types, and many OEM clips are sold individually or in packs. If you’re unsure, bring a photo or spec to a parts counter or consult the vehicle’s service manual for the exact clip type and size.
Summary
Plastic clips are a broad category of lightweight fasteners that secure panels, trim, and liners across a car’s exterior and interior. Known as panel clips, body clips, trim clips, or push rivets, they vary in shape and retention style, and using the correct type helps maintain fit, weather sealing, and quiet operation. When replacing them, match the clip to the original vehicle’s specifications or consult a professional to ensure proper retention and alignment.
