Is it safe to use a damaged heating element for my Kenmore dryer?
Ok, with the pictures its a little clearer.

I would replace that part.  There are plenty of appliance repair stores online with model lookups and diagrams to help you find the right one.

That twist tie is going to melt, eventually.  At least the plastic coating on it.  At best, it will smell terrible.  At worst it could start a small fire. 

The more concerning part is what happens if your superglue fails (from the heat).  The heating coilay end up touching a moving part and get ripped up.  Or the 240V wires may touch something they shouldn't.  If your dryer plug is properly grounded, it should trip the breaker.  If not, it could shock someone.

The proper part probably only costs $5-15.  So might as well do it right.

If I couldn't obtain the part for some reason, I would remove the ceramic block, remove the superglue with nail polish remover, and glue it back together with something designed to work on ceramic in hot environments. Most adhesives will say on the bottle what temperatures they are ok for.
