Not at all.
Can't see me getting over how tedious and annoying I find you now, just as I found you then, dear.
Then stick to that, and stop pretending to be Amanda Wingfield suffering an attack of the vapours.

I can see that you're warming to me, sweetheart......
Have you had your BP checked recently? I'm a little worried about your lack of control, dear.....

why? if there's no need for strain relief ( and there appears to not be unless your duct travels a significant distance vertically ) , then the cable tie is a valid method of securing a cable in place.. they even make sticky bases for them for that exact reason..
my suggestion of using the holes in the din rail is no more silly that cable ties through the holes in cable tray.
the DNO have been known to use earth clamps on the SWA of supplies and several of the larger feeds in our old place had what amounted to copper all band roung the swa and to the earth stud of the isolator for earthing purposes.
anyway, that aside, what about my other suggestion?
It was more the earth clamp than the cable ties that I didn't like.
No offence to any DNO chaps here, but I have higher standards than that.
Yes - some kind of bent metal with holes it shall be. I think I've got some aluminium channel I could use - easy to drill and no bending needed.

"No bending needed"............
That precisecly your problem, BAS dear. You're incapable of bending!

F*cking hell dude, you have an obsession bordering on the autistic!!! How many f*cking forums have you polluted with your own brand of egotistical b*llocks?
If only all electricians did - then the world would be filled with wiring like RF posted recently about in his scout hut.
Why take a short cut when you can spent a little extra time and make a neat job? It's called pride in ones work I believe, and a lot of people are completely incapable of showing it.

Does anyone know where I might purchase an indoor umbrella? I'm sure it might be as useful as gland within an enclosure or a chocolate teapot.....

While you wait for someone to find one for you perhaps you could fill the time by explaining why not using a gland to ensure a good connection to the armour, or using one but leaving it loose, would be a better option than using one or mounting it securely.
And in the meantime perhaps I could see if I can find any examples of you criticising, or poking fun at, someone for not making SWA off properly.

Perhaps the best option will be to gland into a small metal adaptable box? Sounds like a reasonably big enclosure if there's a duct running into it, so you should have enough room.
You CANNOT use an earth clamp on a SWA cable, the cable is in no way designed to be crushed 
You could however use and gland with a pirana nut on it to provide and earth connection and secure it somehow with zip tie, or even a cleat/banding screwed through the boc into the substrate.

Just in support of 1john's statement - here is a note from the standard
Note to the scope on page 1 of BS 951: 2009 Electrical earthing - Clamps for earthing and bonding - Specification
Note 1 These clamps are also suitable for electrically bonding other conductive parts, where at least one is a tube of circular cross-section. Such clamps are not intended for connection to the armour or sheath of a cable.

ok, so cut a piece of 15 or 22mm copper pipe. splay the SWA and put the pipe over the inner sheath and under the SWA. then use the clamp..
the pipe will prevent crushing

Seems like more and more work just to make a bit of a bodge work....
Bracket or adaptable box methinks....

The only time it is acceptable to clamp around an SWA is in an underground resin joint where they supply a sturdy collett to put under the armour to prevent crushing !
