Nope. I've never seen a clip that would make multiple reliable contacts to TO-220 pins and still leave enough of the original pins exposed to plug into a breadboard.
Any time you put more than a few hundred mA through solderless breadboard contacts, you are asking for trouble, so the intelligent thing to do is to move the power circuits off the breadboard and solder their connections. If you solder the MOSFETs to strip or matrix board to make a daughterboard,you can use a right angle 0.1" pitch header on one edge to let you plug it directly into the breadboard, and also put ordinary headers or even screw terminals on the daughterboard to connect the power wiring.
For larger power circuits, or anything that needs a heatsink, its a bad idea to plug the board directly into the breadboard, just due to mechanical issues. If its got lots of interconnects to the breadboard, a ribbon cable with an IDC DIL header on the end is convenient to keep the interconnects organised, otherwise simply use individual jumpers with Dupont pin ends. It will be more reliable if your power module is mounted to the same base as the breadboard so there is no relative movement when handling it.
One occasion where it is useful to add an extra wire to a TO-220 pin in a breadboard is when using LM78xx or LM79xx regulators, as if the common pin comes loose they will loose regulation and pass a volt or two less than their input voltage to their output, probably blowing its load. Soldering an extra wire to the Gnd pin as close as possible to the body allows you to use separate strips for Gnd in and Gnd out so if there is a bad connection the worst that happens is its load looses power.
