Yep. Glad to hear so many solutions for this and as im reading im chuckling because all these solutions makes sense and ive tried some variation of. I love the tape idea. Makes perfect sense. I have gone the route of creating support via legos. I construct what kind of looks like tshaped risers out of them with a nook in the middle for the cord to sit. Theyve Been working great and they are all fully adjustable. I use them to get speaker wire up off the floor as well. 

Cutting a sponge to size works great.

Cheap and simple.

Two turns of electrical tape & it’s nice & tight. I also cut a small wood block & put it under the connector for good measure.

Thanks everyone for your help! Nice to be a part of a forum that actually works. 

But has the sponge been cryogenically treated?  Inquiring minds want to know!
