Best possible fixing for aerated blocks.

OTOH, if you're even trying to attach things to aerated blocks, you're
probably doomed.

Aerated blocks are crumbly and have low tensile strength over very
small areas (only something like 1/3rd of the average over a large
area, AFAIR). So other fixings, including resin, that try to attach to
a small hole are likely to fail by this local overloading. These long
split "clothespeg" fasteners aren't great over a small surfae either,
but they're big enough to be adequate and they distribute themselves
over the largest possible volume, so as to avoid local overloading.
