Yes, I did three things to minimize the possibility of breaking.
First, pre-solder the ends of the wire. It is important to properly heat the wire as the solder is applied so some is transferred up into and under the plastic sheath while not letting the plastic melt beyond getting a bit soft. Exposed stranded wire is very weak and the goal here is to create a small section of solid wire that extends up into the sheath. This is the most important preventative measure.
Second, hold the plastic sheath flat against the board as it is soldered and when it gets soft from the heat, push it down slightly and hold steady as the solder hardens. This will help reduce any gap between the wire and the board which will allow movement and eventual failure.
Third, and only if you are confident in your superglue skills, place a small amount on a toothpick, gently pull up one edge of the plastic sheath and glue to the board. You don't need much and you don't need to glue all the way around, just enough in one place to keep the plastic sheath attached.
Hope this helps. Let me know how it works out.
