The Connection tool is part of the Assembly tools subset and is for moving 3D objects.
What you are looking for is the trim flyout toolbar, there you will find the Connect Curve, Extend, and Corner Trim tools. There is also a Join Curve tool but it can change your geometry and cause some odd looking extrudes, and no, it's not a bug, the program must guess how the curves are to be connected and sometimes it guesses wrong.
If you have any questions on using these tools, just ask.
