Quick answer: they’re generally known as LATCH connectors (lower anchors) and a top-tether clip; if you install with a seat belt, you may also use a locking clip.
Understanding the basic terms
These terms cover the main hardware used to secure a child car seat in most vehicles: the LATCH system, which uses lower anchors and connectors, and the top tether that helps prevent forward rotation. When a seat belt is used instead of LATCH, a locking clip may be involved in some installations.
- LATCH system (Lower Anchors and Tethers for Children) — a standardized set of anchors and connectors that secure the car seat without using the vehicle’s seat belt.
- Lower anchors — the two metal bars located in the vehicle’s seating area that your car seat’s lower connectors latch onto.
- Lower connectors (LATCH clips) — the hooks or clips on the car seat that fasten to the vehicle’s lower anchors.
- Top tether — a strap on the car seat used to secure the top of the seat to a dedicated anchor behind the vehicle seat.
- Top tether anchor — the point in the vehicle (often behind the seat) where the top tether strap is secured.
These terms help you identify the correct parts and follow the installation steps outlined in your car seat manual.
Seat belt installations and locking clips
When a car seat is installed with the vehicle’s seat belt rather than LATCH, a locking clip may be used to lock the belt and keep the seat from moving. Many modern vehicles have locking seat belts or locking retractors that reduce or eliminate the need for a separate locking clip. Always consult the car seat’s manual and the vehicle’s owner’s manual for the correct method.
- Locking clip (belt locking clip) — a small clip used to lock the seat belt around the car seat in installations where the belt isn’t automatically locking.
- Locking retractor (ALR) in seat belts — many modern seat belts lock automatically; in those cases, a separate locking clip is typically not required.
Always verify the installation steps with the car seat’s manual and your vehicle’s manual, because requirements can vary by model and by country.
How to identify the right clips for your setup
To ensure you’re using the correct hardware, look for labeling on your car seat and in the vehicle that references LATCH, lower anchors, top tether, and locking mechanisms. If you’re unsure, consult the manual, contact the manufacturer, or seek hands-on assistance from a certified child passenger safety technician.
- Check the car seat for a LATCH label and locate the two lower connectors and the top tether strap.
- Find the vehicle’s corresponding lower anchors in the seat bight and the top tether anchor behind the seat.
- Read both the car seat and vehicle manuals for any model-specific requirements or prohibition of certain installation methods.
In all cases, ensure a tight, secure fit with minimal side-to-side movement once installed, and re-check the installation after a few minutes of use or after rough road conditions.
Summary
Car seat clips and hardware revolve around the LATCH system (lower anchors and top tether) and, when using a seat belt, a locking clip or locking retractor may be involved. Knowing the terminology helps you identify the correct components and follow the installation instructions safely. Always follow the car seat manual and vehicle guidance, and consider professional assistance if you’re unsure.
