What is this white plastic clip with square foam-looking thing attached to the corner of a pillow underneath the pillowcase in my hotel room?

Answer: It’s a protective cover for the zipper pull tab to ensure no bugs or mites get in. The foam is to keep it from rattling.
Hotels use these plastic zipper covers to protect bedding from tiny intruders such as dust mites and bed bugs. The clip is designed to go over the zipper pull tab of the pillow protector, sealing it securely.
The small foam piece inside the plastic isn’t just for show — it serves a practical purpose. The foam prevents the zipper pull tab from rattling or making noise, ensuring you get a quiet, restful night’s sleep.
Why Hotels Use This System
- Hygiene: Pillow protectors with covered zippers reduce the chance of dust mites, allergens, or bugs sneaking in.
- Noise Reduction: The foam pad eliminates the clinking sound of zipper pulls against the bed frame or headboard.
- Durability: By securing the zipper, hotels extend the life of their bedding and keep it looking neat.
Common Misconceptions
- Not a tracker: Despite what some guests initially fear, these clips have nothing to do with monitoring guests.
- Not a security device: They aren’t alarms or theft-prevention tags.
- Not a hidden camera: The design is entirely functional for bedding hygiene and comfort.
Final Thoughts
Next time you see that white plastic clip with foam on your hotel pillow, you can rest easy. It’s simply part of a pillow protector system used in many hotels worldwide to keep bedding clean, fresh, and quiet.
So instead of worrying, consider it a small detail that ensures your stay is more comfortable — and bug-free.
