Crius clips - attaching anything thin or flexible to any pipes securely and economically

This is my new awesome "invention" - Crius clips.

You can secure a thin or thick gauge steel wire to any pipe securely without slipping.  There's no slipping.

You can attach a towel or a plastic sheet on to a length of pipe for shelter or projects.  Not even high winds can detach it.

Say if your pipe is 1/2" PVC, pick the next size PVC pipe, which is 3/4".   Use a pipe cutter to cut out about 1/4" length of pipe.  From this O-ring, cut out about 90 deg, or a corner.  The remaining PVC pipe is a Crius clip.

Place the C opening on the pipe you want to clip on.  Push the clip on with your finger and it will go in easily.  It takes two hands to take it back out.

The clip itself is always PVC pipe.  The pipe to be clipped on to is not limited to any material.  For example, for galvanized steel 1/2" EMT pipes, the best clip is to be made from 1/2" PVC pipes (the OD is slightly larger than the EMT pipes).

If you want to clip thick power supply cable or a thick carpet, use two size larger PVC pipes.

I'm into PVC and EMT gadgets and found numerous uses for this Crius clip.

Environment issues: The manufacturing and recycling of PVC involve toxic materials.  PVC itself is stable and harmless as used in drinking water.

PVC and CPVC are supposed to replace expansive copper pipes.  There's no going back to copper as I myself witness micro pores that can form on copper pipes.  This is a nightmare as a leak can develop in any length of pipe.  The leaking can continue for a long period undiscovered.  The reason is still unknown.

The newer PEX are superior in many ways.  But I heard that rats like them too?

PVC will be around for a while.  They are also used to replace metal and wood window frames for energy efficiency.  They are not that environmentally friendly but they last a long long time.  They can be recycled too.

I can't find anything to replace PVC furniture.  Metal couplings cost 10 times more, and they are bulky.

PVC produces toxic fumes when burned.  Ironically PVC window frames and very popular.

There are ways to reduce PVC in furniture though.  For pipes that don't need to be tight fit, you can use steel EMT pipes that is about the same price.  You can still use PVC couplings but they won't exactly fit.  You can use loose pipes, for example, for the horizontal support of beds.  Or for vertical grids to keep things in.
