To inject a little reality here, the difference in pressure between an EVA suit at Earth Sea Level pressure and vacuum is a little less than half of the difference in pressure between the inside and the outside of a properly-inflated automobile tire. Anything that can stop (or slow) the loss of air from a tire puncture would be adequate for an EVA suit puncture.

As for "fixing" with a tourniquet, if your suit is leaking and the leak can not be stopped, it may be preferable to seal off the leaking section and lose half an arm to the vacuum than to let your entire atmosphere escape and suffocate.
