I believe these were called "scotchlocks" by 3M. It's a shortcut to wiring the right way. That's fine if you don't need or not concerned about a bullet proof connection.
The effectiveness of a scotchlock is subject to the intallation technique, the insulation, vibration, stress, exposure to the enviorment and time. On the other hand; you can crimp, solder and heat shrink once and forget about it.
As long as you understand and accept murphy's law, some might be content with twisting the wires together and taping them off.
