Climbers (and cavers etc) use karabiners which are a little bit like the
clips Bill mentions. But some karabiners have screw gates (as Alan P
mentions). These screw across the gate (sic) to stop them opening by
accident. Climbers etc who want to grow old use ones with screw gates
when their safety depends on the gate staying shut.

Damm right they do. We use them for climbing on masts and I've seen one
of the open gate ones come off where it was clipped on. Fortunately all
it was doing was holding some tools...


A question for Bill: do all your cable ties stay flexible that long?
I'd always assumed (albeit for no good reason) they would fail after
flexing a lot especially in low temperatures.


Some ties are better than others..
