Broken Negative Battery Clamp!

So i was installing a new steering wheel emblem, and had to disconnect the negative battery terminal. When i was all done, i went to hook it back up. As i was done tightening the 10mm bolt, i realized that the clamp wouldnt stay on the battery, it just pops right off and when it does so, the car shuts off.

basicly, is there a way to fix this other than putting a new negative clamp on? its honestly barely staying on . Any advice would be nice
