Is Re-wiring the Battery Cable Safe?

We recently had an issue with my 2010 PT Cruiser where the clamp on the end of the battery cable (that screwed to the post of the battery) got a small crack in it. This caused the wire to slip off and we lost juice to the entire car. This particular clamp had a weird connection, as the end of the battery cable came out to two separate prongs that clipped to it. We could not find the two-prong replacement clamp, but there were the traditional one-pronged style in abundance at Auto Zone.

So what we did as a temporary fix is cut the batter cable prongs off, twisted the bare wires together at the end to form one solid cable, then screwed that down to the clamp and connected it to the post as normal. Everything is working great now. We checked with a local mechanic and he said that's a common practice. We also checked out the batteries of several older model PT Cruisers and they all have the traditional one prong end on the battery cable instead of double like mine.

So my question is it safe/OK for my cars performance to leave the one side of the battery cable merged like this (with the other side still using the factory two-prong design)? As I said, everything is working great and the current seems to flow perfectly.

What are your thoughts?

    A twisted splice is never a good idea...it should be soldered and even then it can't really withstand flexing of any kind. Is this the positive or negative side?
