A fresh link for this part - http://www.peeron.com/inv/parts/55615. It's called "Pin connector perpendicular" in LDraw.

<p>Is there a way to connect the two beams in this angle and still keep the connection strong and keep the rotation the same?</p>

By the way, if you're after strong connections, I would also suggest replacing your grey Technic pins, which are frictionless, by black ones, which will lock the beams better into place. The difference might not be huge, but it may help.
