Years ago when I bought the analyser I use now most of the time I was
a bit worried about the way the carrying strap was fixed to the case.
It had those things like you get on dog leads, that just clip onto the
collar. I put loose cable ties alongside these clips, just in case one
of them ever did accidentally unclip itself. Last week I was climbing
a scaffold ladder with the analyser on my back when I felt something
brush against it. At the top I had a look and sure enough the clip had
been unclipped and the only thing saving the analyser from a 50ft fall
was the cable tie.

Cheap option :-

Use 2 cable ties on each clip.

Expensive option :-

2 x carabiners ( e.g. Clog HMS Screwgate £10 each )
Will work for a lifetime and can be left in your will.

I should have realised this, but didn't until I read this wiki, that
these were originally designed to support firearms :-

The Clog one above can be purchased online from :-

Not sure of urls, but Ellis Brigham, Field+Trek, et al should sell
them.

There are Blacks at Meadowhall, and on the High Street in Sheffield,
but they are unlikely to stock carabiners as they do not specialise in
climbing equipment.
