I have to tell you, one of the most innovative splice connectors I ever used was the AT&T/Lucent/Avaya/Commscope 709SC and SD. I don't know if they are still being sold, but I really liked them. They are in-line and handle a full pair-in and out. Filled (SC) or dry (SD). They can be crimped with fingertip pressure, but it takes a lot. The nice thing is that they were designed to be crimped with needle-nose pliers (the crimp area was arched to allow for the angle of any kind of pliers). They are really hard to mess up.

The only thing that I didn't like was the half-tap feature. You had to break off one of the end caps and replace it with a microscopic replacement cap that allowed a pair to run straight through. Too much work and room for error.
