/ Small steel self-locking krab?
The closest that I've found so far is the Petzl Oxan, but it looks a bit on the big side and ideally it needs to be a D/offset D shape too.
DMM do 10mm steel D karabiners as screwgates, double or triple action twistlocks:
Oh come on, surely you can't seriously expect to start a thread with those words and get away with it?!
Looks promising, thanks. I might pick one up and on the off chance it's no good for her I'm sure I'll find a use for it.
She's a trapeze artist and is looking for a krab for her end of her lunge rope (the thing that stops her dying if she falls off). She wants a self-locking krab because she's had screwgates undo themselves before, and it needs to be fairly compact to not get in the way or be annoying. She'd also prefer it to be steel for personal peace-of-mind reasons.
The inconvenience of five seconds with a spanner might be worth it for the compactness and peace-of-mind.
Seconded Maillon suggestion.
Compact, secure, strong...steel!

Regarding this bit - if she thinks an aluminium carabiner won't be strong enough, that's an irrational fear and possibly one worth working at to get over.
If size/weight are important, two DMM Phantom screwgates back to back would still be less than half the weight of a steel screwgate/twistlock/whatever.
If there's time to do it up and check it, I'd second (third) the suggestion of a maillon. You'd be wanting a proper PPE rated one, available down to 7mm in stainless steel and ridiculously strong: http://www.peguet.fr/gb/produits/EPI_industrie-EPI_montagne_normal.html
A maillon wouldn't be suitable as she needs to be able to clip in quickly before her routine. Having to break a spanner out in front of a full audience probably won't go down so well! Similarly, reversed krabs or anything other than the minimum of faff is no good either.
Her preference for steel is more for inspection and longevity purposes rather than any worry about strength. The krab she's using at the minute is aluminium, but it's a decent-sized HMS and she's not entirely happy with it - so I thought I'd see if I could find her 'ideal krab' for Christmas...
Why does it need to be small? If it is a visibility issue then maybe a matt black anodised army "stealth" screwgate (as made by DMM and sold in - I think - V12 Llanberis) might do the trick - if they have a self locking one.
If there are other reasons it needs to be small then please ignore me :-)
My own trapeze-artiste friend just spent 8 weeks flying around on stage in an Aladdin panto :-)
How about a magnetic locking karabiner?
A Belay Master? Won't cross-load, and the plastic clip over the screw means it is less likely to come undone (and she won't forget to do it up, as is a distinct possibility). And they aren't very big.
I think "speedy and slick" is the order of the day here, if I understood the OP's later posts correctly.
In the end I ordered one of the Foin self-lockers and she seems happy with it. The size thing isn;t really about visibility but about getting in the way. Her current krab is apparently a bit big and slightly annoys her and gets in the way. Not being a trapeze artist myself I'm not entirely sure why though.
Problem solved eventually though, thank you for all your help (and the brownie points thus received...)
That may be more to do with your not being a girl, than not being a trapeze artist....
