Trailer anti-theft devices for car and utility trailers
Secure your trailer reliably against theft
Coupling locks and wheel clamps for different trailers and parking situations
A trailer anti-theft device makes it more difficult for anyone to couple up or move your trailer without permission. Coupling locks, covers and wheel clamps protect different points of attack. The right solution depends on the coupling, the place you park and your required security level.
A coupling lock is fitted directly onto the coupling head. It is especially suitable for short stops and regularly changing parking places. Some models can also be fitted to the coupled trailer while driving. Always observe the advice given on the respective product page.
Covers are also fitted onto the coupling on the drawbar and are available in different security levels. Compact variants allow easy handling. More robust models offer extra drilling protection or meet the requirements of international security certificates.
The AL-KO PROSAFE wheel clamp locks the wheel of the trailer. A special wheel bolt, supplied with the product, remains permanently fitted after the initial installation. The wheel clamp is suitable for caravans and utility trailers.

- Coupling locks block the coupling mechanism and prevent unauthorised coupling or uncoupling.
- Covers enclose the coupling head and, depending on the model, also provide protection against drilling or disassembly.
- Wheel clamps lock a wheel and prevent the trailer from being towed or pushed away easily.
- A Safety Ball closes the ball socket on an uncoupled trailer and complements the coupling lock.
- Several visible security devices increase the time and effort needed for a theft attempt.
Which trailer anti-theft device is suitable for which situation?
- Short stop on the road: A quickly fitted coupling lock makes it more difficult to uncouple the trailer without permission.
- Parking on your own property: A coupling lock with Safety Ball protects the coupling head on an uncoupled trailer.
- Longer periods of parking: A wheel clamp locks the wheel and provides a highly visible mechanical barrier.
- High-value trailer: Combine a coupling lock and wheel clamp to cover multiple points of attack.
- Trailers with AK 161 or AK 270: The Safety AK 161/AK 270 is specifically made for these couplings.
- Other coupling systems: Before purchase, always check the product name, coupling type, diameter, and installation situation.
Frequently asked questions about trailer anti-theft devices
Secure at least the coupling head with a suitable lock. For longer periods of parking, it is advisable to use a wheel clamp as well. A well-lit and protected parking place complements mechanical measures.
The best security device matches the coupling and the type of parking. For high protection, we recommend a combination of coupling lock and wheel clamp. No mechanical device can ever completely rule out theft.
