Was it an edge connector similar to: http://www.greenwayproducts.com/buy_tortoise.shtml ?
Since when does a Tortoise machine ever burn out or need to be replaced? That's the real question. My club has hundreds of Tortoise machines on our layout, and we've had then installed and in use for 8 years or more. Not one has ever needed replacing (there was the one Tortoise that got drilled into by someone installing feeder wires, but that doesn't count).
Sure, there may be one that goes bad...someday. But the fact is that Tortoise machines are very dependable. A quick disconnect edge connector is a waste of time & money, IMHO.
At our club, we have some 8-conductor cable that we cut 12" to 18" long, which we solder to the Tortoise machine on the work bench (color coded, of course). When we install the machine, the wire dangles free, and is used to test the machine's operation with a 9v battery. After installation, the 8-cond. wire is then trimmed to length and secured to an 8-position terminal strip (usually a Euro-type), which in turn is secured to the layout. This terminal strip is where all connections are made to the layout for power, frogs, and indicator lights. It also makes a great strain relief for those that might tug on the wires.
The beauty of our system is that no soldering is done under the layout. If you've every dripped solder into your face or lower body when soldering above your head, you'll appreciate that.

If you want to use some sort of plug-in fitting, I would just solder Molex pins to the Tortoise. Far more reliable connection than the edge card connectors - even the ones specifically sold for the Tortoise aren't a perfect fit, plus the cost far more than 'generic' endge card connectors from an electronics supplier. And the Molex pins are cheap.
However, between the ones I used for myself and the club I used to belong to, I've never seen one fail. Even one I had that I took apart to see what was inside, and otherwise abused by manually moving it back and forth as fast as I could, still worked fine, if a bit noisily. I see little reason for attaching expensive connectors of any type to one. My layout height is such that I don;t have to be laying on my back to solder underneath, I'm more or less sitting, so there's little danger of solder dropping on my head, so I don't even worry about that.

Our club had one turtle fail and it was a plastic gear the came off the metal shaft. I took it apart and used a tiny bit of 5 minute epoxy to fix it on the shaft.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
I looked at those a while back and like the rest just didn't see the need. I can solder my leads to the tortoise just as quickly as screwing them to a terminal block and much prefer soldering. In fact I enjoy soldering. Much better places to spend your money in my opinion.
I've tried a few different approaches, including the edge connector, direct solder, remote terminal strips and the best solution for me has been to solder PCB screw terminals to the Tortoise solder traces. This gives you the option to wire in place, without having to solder beneath the layout, it's easy to replace a tortoise, and it gives you the ability to still move wires around (which I do often).

I think they released the edge connector with the new Smail, which is a tortoise with a built in Accessory dcc decoder. I haven't tried one yet but will soon.
