The 3/8 brass coupler is from Home Depot ($2.70). Ground down the pipes and enlarged the hole, then used the rest as a bracket. The clamps are fuel injection clamps. Should last forever.
OMG IMOOO, i did this EXACT same fix a year ago. I broke mine doing my water pump. I was to take the car on a trip the next day, off to home depo i went.....
Great idea. I did a similar fix when I changed out my water pump last year. I also changed out the tee that is also prone to failure. I hope that there are no issues with dissimilar metals, ie brass and aluminum, and the Porsche coolant.

Good point. Use of dissimilar metals may set up a corrosion cell, leading to premature failure.

Are you on crack?
If the coolant is not acidic, and it won't be unless it's really, really,really old, nothing will happen. Even if it id, the brass will develop a layer of corrosion and stay that way. Porsche used plastic because it's a hell of a lot cheaper than brass.
First of all, I did this same repair because the plastic piece broke. It was so brittle from age that it just crumbled in my hands. I used a brass coupler and did the exact same thing with the bracket and clamps. I will never worry about that fitting again! Now, for a bit of chemistry...galvanic corrosion occurs when dissimilar metals TOUCH each other. Unless they are in electrical contact, there can be no galvanic couple set up. The brass is electrically isolated due to the rubber hoses, so there is no need to ever worry. For those that are truly way over thinking this one...you can get a electroless nickle or stainless steel hose barb fitting. As for the rest of us, well, with 120,000 miles and 13 years on mine...I'll give you an update in another 100,000 miles/10 years and let you know how it goes.

Thanks, I just did this exact fix and filled it with coolant. So far no leaks.
I'm amazed at how easily that fitting cracked apart initially; when I tried to pull the fitting from the other hose it snapped off on that end too.
Thanks to everyone for your help and suggestions! It really helped to see pictures of the part since I had no idea how it all fit together.
Well, since we are dragging up an 8 year thread, might as well throw this in. The problem I noticed is the lower hose and upper hose are slightly different. I had that clamped off very well and still developed some leaks at the fitting. Yes, I did use a brass barbed fitting and two new hose clamps. I never really liked the overall solution, so I bought a new OE lower hose and got this. Never a single problem now and I don't have to even look at that fitting unless I want to admire this new fitting. Well worth the money.
Another happy customer of Rauch & Spiegle. It should be included as apart of water pump/t stat job if you don't already have one. I busted the original replacing the oil filler neck..while removing the alternator. So many opportunities to break this thing.

Easy and cheap coolant line coupler fix.
