small connectors with strain relief?

[Tim Shoppa]

I don't think your going to get any better than the RTV.

Its cheap and it works.

All it does is guarantee that when the wire does break, it'll break at
the end of the RTV. It also removes the strain relief provided by the
insulation crimp and the connector housing, and takes away some room
for the cable to flex, and it'll make the wire break with fewer stress
cycles.

It is cheaper than the proper crimper (they run several hundred $ to
low thousand $ for a certified crimp!)
