I've never heard of a banded crawler (and I've been interested in spiders for about 30 years) so I've no idea which species Collins are referring to, but this is a Salticus species, most likely S. scenicus, which is a type of jumping spider. I have heard this species called zebra spider, but never banded crawler.
The 'Banded Crawler' as included in the Little Gem photoguide is Poecilocroa conspicua - which is a typo for Poecilochroa conspicua (Simon, 1878), that is a synonym of Kishidaia conspicua (Koch, 1866), its current combination. Your spider is definitely not that species and is as jaguarondi says a salticid spider, Salticus, which you will find on page 221.
This highlights a problem with 'liitle guides' like this Gem spider book - in its intro it states that the book contains 200 species (of the now 50,000 or so described worldwide) that have been selected for their special interest, appearance or abundance. What this makes this book is a tantalising snapshot of 'interesting' (and less interestin) spiders, almost certainly driven by the images that were available, of spiders from around the world. Thus there is a very small chance that you will be able to spot very many of the world’s spiders using this book as an identification guide. As far as UK species are concerned there are just over 60 UK species illustrated but unless you go specifically hunting for spiders in the UK there are only about 15 species that you are likely to come across by chance in homes or gardens.
In summary - the kind of book you might flick through while waiting to get your teeth filled or your tyres cahnged (though I have never found anything as interesting in either of these waiting rooms); whereas the Collins Field Guide to Spiders of Britain and Northern Europe by Michael Roberts is a far more accomplished and useful guide. Get if from the library (yes they still exist) or bookshop (old fashioned, online or otherwise). http://www.amazon.co.uk/books/dp/0002199815
