As for strain relief, you can get fusion tape (rubbery stretch-and-wrap stuff that
becomes a solid blob) wrapped around the hand-soldered connection, and an overall
layer of heatshrink tubing, which replicates most of the mechanical advantages of
molded connectors, and is just AMAZINGLY ugly. And, it works.

Yeah, those usually end up in the "My eyes! The goggles do
_nothing_!" category of ugliness... and, yeah, they're sturdy enough
that the fusion, the strain relief, the protected solder joint, and
the whole wiring job will usually outlive the one who made it.
