Encrypted Checkout
Your tow hitch is one of the easiest things on your vehicle for someone to walk off with. A standard hitch pin and clip can be removed in seconds, taking the tongue and tow ball, a bike rack or a recovery hitch with it. The RV Essentials Australia Hitch Pin Lock replaces that open pin with a keyed locking pin. The hitch stays put until you unlock it.
What Is a Hitch Pin Lock?
A hitch pin lock is a locking version of the pin that holds your tongue or accessory in the vehicle's receiver. It is not a coupler lock and it does not lock the caravan or trailer coupling to the tow ball. Instead, it secures whatever is fitted into your receiver, such as a tow ball tongue, bike carrier or hitch-mounted recovery point, to the vehicle itself.
This lock uses a straight pin with a detachable, key-operated lock head. Slide the pin through your receiver, fit the lock head onto the end and turn the key. To remove it, unlock the head, pull it off and slide the pin out.
Why Choose This Locking Hitch Pin
- Keyed security – a tubular key lock head replaces the standard R-clip
- Tethered dust cap – covers the keyway when the lock isn't in use
- Knurled grip – textured barrels make the lock easier to handle
- Black finish – a clean look that suits most tow bars and receivers
- R-clip included – a standard clip is supplied in the pack
How to Check It Fits Your Tow Bar
Hitch pins aren't one size fits all, so take two quick measurements before you order.
1. Pin diameter
Measure the pin you use now, or the hole it passes through. The pin on this lock is 15mm in diameter, according to the supplier's dimension drawing. It needs to pass freely through your receiver and tongue holes without being loose.
2. Usable pin length
Measure across the outside of your receiver where the pin passes through, from one side to the other. The usable length between the two ends of this lock is 84mm, according to the supplier's dimension drawing. Your receiver width must fit within that length, with enough clearance for the lock head to seat properly.
Not sure?
Send us your measurements or a photo of your hitch and we'll help you check before you buy.
Who It's For
If you tow a caravan, camper trailer, boat or box trailer, you probably leave the tongue in the receiver more often than you'd like to admit. It's convenient, but it's also an easy target when you're parked at a caravan park, a shopping centre or a trailhead. A locking hitch pin is a simple, low-cost way to make that set-up harder to remove. It's a sensible addition alongside a coupling lock and wheel clamp on the trailer itself.
A Realistic Word on Security
No lock stops a determined thief with the right tools and enough time. What a hitch pin lock does well is remove the easy opportunity, so a thief can't just pull a clip and walk away. Layering security, like locking your hitch, your coupling and your trailer, gives you the best protection.

Will this hitch pin lock fit my tow bar?
Check two things. First, the pin is 15mm in diameter, so it needs to pass through your receiver and tongue holes without being loose. Second, the usable length between the ends is 84mm, so your receiver must fit within that. If you're unsure, send us your measurements and we'll help.
How do I measure my receiver?
Use a tape measure or ruler across the outside of the receiver where the pin goes through, from one outer face to the other. Then measure the diameter of your current pin or the hole. Compare both figures with the pin's 15mm diameter and 84mm usable length.
Is this a coupler lock for my caravan?
No. This lock secures the tongue or accessory in your vehicle's hitch receiver. It doesn't lock the caravan or trailer coupling. For that, you'd need a separate coupling lock.
How does the lock work?
Slide the pin through your receiver, push the lock head onto the end and turn the key to lock it. To remove it, unlock the head, pull it off and slide the pin out. The tethered cap covers the keyway when you're done.
Will it stop my tow hitch being stolen?
No lock can stop every theft. A hitch pin lock makes your hitch much harder to remove than a standard pin and clip, and it deters opportunistic thieves. For the best protection, combine it with a coupling lock and wheel clamp.
