For christ sake just clip it in it takes about 3 seconds if that.
But I keep forgetting
bet you don’t forget to put your ■■■■ away before coming out the bog do you
Here in France a dogclip isn’t a legal requirement, yet our firm has seen a fair few dropped trailers (thankfully not on public roads) so now certain depots are fitting them to all their units. Seems to make sense…

This has got to be a ■■■■■■■ wind up?

Fasten post-it note to the dash using a dog-clip & chain!!!
My trucks never had one. Delivered brand new without it…

May be wrong but if you have a fifth wheel with a latch, this should be sufficient as a secondary locking device. Think Iveco with the pull out handle with no dog clip

Above is for a Jost coupling. The spring clip is enough in my eyes. Legally you do not need a dog clip as well as the spring clip, although some people do fit them.
I’m uncertain dog-clips would really prevent trailer loss. Generally trailers are either coupled properly, or they’re not. If the dog clip goes in it’s more likely they are but the only real way to make sure is to get under with a torch. Their main benefit is probably in making it difficult if some ■■■■ decides they want to pull the pin.
Bit similar to susies where twisting the collar is good to ensure they are properly on but probably wouldn’t come off if you didn’t provided they are on properly.
Nothing illegal with padlocks but they are hard work to get off, due to the access, if they’re left on so long they corrode or the key gets lost.

On a few occasions I’ve forgotten to put the dog clip on. Never lost a trailer so they’re pretty pointless if you ask me. I know I would get nicked by vosa if it’s just hanging, but what if I took it off? Surely the can’t do you if it’s not there
I wouldn’t say they were pointless, I’d say they were a legal requirement in the UK, try getting by one of your VOSPA geezers with it unhooked. I wish we had them here but I have not seen one on any truck at any time, peace of mind goes a long way.
They wont make a unit hold onto a badly/not fully coupled trailer, but the clip fitting does force one level of check, which some morons wouldn’t bother with otherwise. The main way they stop a ‘dropped trailer’ if when it IS coupled correctly, and then in the 0.01% chance the main spring in the 5th wheel brakes AND it then hits a bump on a LH turn, it could jump out, as the spring is all that stops the handle being moved out and across- unless a dog clip is there…

The main reason trailers come detached is through driver error, badly maintained or damaged jaws. I have posted dozens of times about the problem with the PTFE or steel bush that is fitted in many types of modern fifth wheel apparatus, Jost, GF+ etc
The dog clip only prevents the release mechanism working or being messed around with, the chain doesn’t hold the trailer on or apply the brakes like a caravan breakaway cable.
For sure, I totally agree that 5th wheels are one of the most under-inspected parts of the truck. We regularly clean them right down to inspect/check wear before re-grease, but have heard of lots of people trying to adjust ‘slack’ out when its in fact the bush/plate thats worn/battered as you said. But that said trailers wouldn’t ever get dropped if everyone (maintenance & drivers) did their job correctly every time. Too many companies out there pile the pressure on to drivers and the compromise is safety/short cuts in one way or another.
