Evening all,
Quick question , if the little lug that locks the collar in place is missing VOR or not ?
Thanks
no get it sorted asap
Hmmm…don’t know but suspect it might be?
I would think so as there’s nothing to stop it popping off
No not VOR just get it sorted ideally before you leave but if not ASAP

Yes it is VOR and VOSA will have something to say about it at a roadside check.
Thought so turned up at work tonight at 21:15, no transport staff in just get keys off security, I VOR it seein as though I noticed while at yard I defected it and got new unit , probably wouldn’t have come off but didn’t fancy driving all night with that thought in my head.

Given an awful lot of drivers don’t bother twisting the collar there definitely is something to stop it popping off.
Just take extra care it’s connected properly and get it sorted asap. Vosa won’t have any interest unless it’s ■■■■■■■ air out.
There’s a thread on here about what happens when the red airline fails at high speed. Read the post I made in that thread. That was with a missing lug.
I have to admit that in the past if I found it missing it would worry me as I would always turn the collar after connecting the air line, I had the feeling that once the collar was turned that little pin would prevent that collar sliding back in some error, I always got the susie replaced ASAP.
It’s been 14 years since I used such things as we have ‘glad hand’ or palm coupling’s as you call them on the trucks here.
Parking and Emergency Brakes
This inspection applies to all vehicles and trailers.
Heavy Goods Vehicle Inspection Manual
12 Trailer Parking and Emergency Brakes and Air Line Connections Application
Air Line Connections
This inspection applies to all trailers of whatever age and to drawing vehicles first used from 1 April 1989.
Emergency Brake and Air Line Connections:
ï‚· Ensure that the air reservoirs on the drawing vehicle are fully charged.
ï‚· With the vehicle parking brake on and the trailer parking brake off, ask the driver to disconnect the service (yellow) and
emergency (red) brake lines.
ï‚· Check, on vehicles and trailers fitted with “C” type couplings, that the coupling in the service (yellow) line - either fitted to the
trailer or in the line itself - is fitted with an operating adaptor which can open the self sealing coupling in the connector from the
drawing vehicle.
ï‚· Check that the operating adaptor lifts the indicator on the test coupling by the correct amount. The waisted portion (coloured
section) of the indicator must be exposed, but no more than this. This does not include additional couplings which may be used
on trailers such as extendable types.
ï‚· Check that any brake line on the drawing vehicle is not fitted with a manual shut-off tap. Additional taps fitted to extendable
trailers are not included in this inspection.
The driver must be instructed to reconnect all couplings before the vehicle is moved
When presented, the tractor unit must be compatible with the trailer and have a warning lamp to indicate that trailer ABS is working (This may be a combined ABS/EBS warning light).
If presented with a compatible EBS tractor unit, if the red line is dropped, the brakes may not come on. To apply the brakes disconnect the ISO 7638 electrical connection. Ensure that the handbrake is applied on the tractor unit before disconnecting the red line and that safe working practices are followed.
Provided self sealing couplings are used on the tractor couplings it does not matter whether the air adaptor couplings are the conventional way or reversed.
Some park brake controls also deplete the air suspension systems when the red air line is removed, this is acceptable provided it does not drain the air brake reservoir. If it does the vehicle must fail under RfF 5a of section

I doubt the collar would move just because the lug is missing, except in some exceptional circumstances, just think about the action it take to remove a red air line. However in these days of where there is blame there’s a claim and companies having to cover their arse in case they get sued, I wouldn’t use the truck until it was replaced.
Funny you mention the suspension issue neversweat. I had that happen to me, the red kinked and when I pulled in for my compulsory coffee stop to investigate a red ABS fault, the trailer stunk of brake dust and the back mudguard was touching the tyre.
I found the trailer brake had no pressure behind it and the red airline was the same, it had kinked, unlinked and put it back on and the trailer “bounced” back to position and off I went.
I had just reloaded and assumed it was the weight pulling me back. Just as well I stopped when I did.
Just to add it kinked on the curtain tensioner then popped off. Must have been while I was pulling off the bay.
