I have plenty of cable clips that work great indoors, but I want to attach a cable to an outside pebbledash wall. The existing cable clips, which have broken, appear to have been nailed into some kind of plug, but I can't see what.
What is a good technique for attaching cables to a wall that won't accept a simple nailed clip?
No, you can't because that's not an electrical box or cable but is rather a telecom cable and bracket.
It's going to depend on the type of framing used. Balloon and platform framing are the two common methods.
If you're dealing with platform framing, you're going to have to drill through quite a bit to go between floors. First you'll hit the bottom plate of the upper wall, followed by the decking (subfloor). Next you'll hit a double top plate, which once you're through you'll be in the lower wall. Since it's a common wall, you'll also likely have to deal with blocking and insulation.
If it's a balloon framed structure, you're lucky. You'll likely only encounter blocking, bracing, and insulation. However, these elements are a bit less predictable, so you'll have to take things as they come.
Any time you create a passageway for fire or gases to pass between floors, you'll have to provide adequate fireblocking and/or draftstopping. This could be as minimal as some fire resistant spray foam, but you'll have to check with your local government to determine what's required.

The original solution turns out to be bits of hardwood doweling inserted into the wall, with the cable clips hammered into them.
