Adhesive to handle extreme cold, but one I can melt at about 75C

[Higgler]

I have a RF cable placed inside a tube which blind mates with the mating connector located on a back wall, and It's difficult to secure the cable, I can only push it in, no mechanical connection other than tynes and spring blindmate contact. I don't want the cable to move during travel. I'm handcuffed with solutions.
RF cables that blind mate bounce around.
I'd like to add adhesive/epoxy/RTV in the tube to stabilize the RF cable at it's mating connector.
One thought is foam in place, or RTV in place, or ? you suggest.

We need to remove this cable, and the added foam/RTV/? for depot repair occasionally.
Our max temp isn't too high, maybe 70C.
So if material flows, and rehardens, that might be acceptable.

Suggestions?

Hot melt glue.

If the objective is to prevent movement rather than provide mechanical bond, would a wax or gel be an option?

Objective is to prevent movement.
In a former company's warning letter, all blindmate connections should be staked with epoxy.
I'm under the impression that epoxy is very difficult to remove from a tube. I wish to use heat to soften the material so that I can pull the blindmate cable out, partially clean out the tube, then replace the cable. Using a chemical to melt the adhesive material is a thought, though a chemical to melt the adhesive and vacuum out is an option.

Yes, a gel or glue would work. I assume Hot melt glue is good at extreme cold? or does it crack?
I'll be doing vibrational experiments under temperature and will need to evaluate a few adhesives.

I know of one adhesive called "liquid nails", which melts at 200F. Not sure it has cold strength though. I wouldn't want the adhesive to crack at extreme cold.

Thanks for the inputs, and any more you can suggest.

What does "extreme cold" mean to you?
