Thanks for the confirmation, Roger. Heat shrink tubing lined with hot
melt glue is readily available in Europe. I use it a lot for
waterproofing, and also to increase the pull strength on small
connectors and cables.
Yes, it does peel off quite easily after slitting with a knife. If the
connector is going to be re-used with heat shrink, there is no point in
removing any scabby residues of glue (think of it as a 'primer coat' for
Before applying the heat shrink, it is also possible to add extra glue
from a glue gun - for example, to fill the gap around the rear of the
connector where the tubing doesn't shrink down very well. This gives the
connector even better pull strength, and it will still peel off if
