Swiss top retaining pins

Better picture to follow Dan. Near midnight now
Appreciate your input.

The pin needs to be pushed in further, try it without the pad and it should go through both holes. A pair of long nose pliers may be needed.
You can see how the pins should look here: https://youtu.be/wFWBHVnJVSw?t=30s

Thanks Mcspud. I'd searched on YouTube and hadn't managed to find anything but your clip is great.
Watching the whole thing I can spot 2 types of clip. I have the fatter one. I'm pretty sure that they came with the pads. Maybe I need thinner ones?
I can see how they should push further down but being ' fat' they don't want to go deeper. All 4 protrude. And 1 keeps wobbling out.
I'll spend more time today trying to get them to sink right in.
Should they ' clip' in? By that I mean, the end clip over the side of the pad?
Thanks for your time and help.

Hi Matt,
Looking at replacement shimano cartridges on SJSC's website the picture shows both types of retaining pins: https://www.sjscycles.co.uk/brake-blocks/shimano-brr550-m70ct4-cartridge-brake-inserts-fixing-pins-y8a298060/
Have you tried inserting the pins in the holders without the pads in place?
There's a thread about it here: https://forum.cyclinguk.org/viewtopic.php?t=93665
As Brucey says there "if you don't want to alter the toe settings, and you do need better access, you can take the entire brake arm off the bike (one M6 bolt) instead of removing the brake shoe from the arm."
As for "Should they ' clip' in? By that I mean, the end clip over the side of the pad?", no not to my knowledge.

Problem solved
Many thanks for links and advice
I pushed all 4 pins right down until the day end hooked over the brake pad holder.
There wasn't always a clear run through due to a slight burr on the inside of the blue pad. Once smoothed out the pin went right down with its end hooking over.
They sure won't be coming out now.
Not impressed with the LBS!
Pictures not good but show pin going right through.
Once again appreciate all comments and links.
