Use 100% silicone adhesive like PL700.
Silicone rubber is the most difficult polymer to join to anything using adhesives. It can be done cheaply, if care is taken. Here's one way.You will need:100 grit emery cloth or silicon carbide abrasive paper.CRC Brake Parts Cleaner. Green can (Non-Chlorinated). This contains heptane, an activator/bonding agent for RTV silicone.GE Silicone I Waterproof Silicone caulk. NotSilicone II! Comes in caulking gun tube - around $4.Cheese grater - the cheap box kind with the sharp super-fine holes for scratching.First try to roughen the steel using 100 grit silicon carbide paper or emery cloth. Then thoroughly degrease and clean using CRC brake parts cleaner.Roughen the surface of the silicone rubber with the cheese grater, and spray with brake parts cleaner.Spread a bead of the silicone caulk in an appropriate amount on the steel. Before positioning the silicone rubber into the caulk, lightly spray it with the brake parts cleaner. Then position the rubber and press it onto the caulk. No need to clamp. Allow a couple hours for handling, 24 hours for full use.Good luck and YMMV.
They are made out of silicone rubber
"Rubber wristbands are commonly made from silicone-a durable synthetic resin. Silicone is rubber-like but unlike rubber, valued for being heat-resistant and latex-free."
Have You Tryed Super Glue?ANS 2 - Super glue will NOT stretch when the rubber does, don't waste your time on it for this joint. -Liquid rubber glue as comes in bicycle tire patch kits is far better !
Epoxy or silicone.
Try a silicone adhesive, such as Devcon. This adhered well to a %100 soft silicone rubber part I needed to glue onto some insoles.

Silicone glue is a type of adhesive that contains silicone as the main component. It is known for its flexibility, resistance to high temperatures, and waterproof properties. Silicone glue is commonly used for sealing, bonding, and repairing various materials including glass, metal, rubber, and plastics.
Any silicone based glue will bond to silicone rubber. -Aqua Seal, Seal All, Goop, Plumber's Goop, Gloozit, PL premium to name just a few that will work.
It's a silicone based glue, that will bond leather and rubber. 'Shoe Goo' is very good.
Steel, aluminum, rubber, silicone, oil, etc

Silicone is best for that.
With a silicone or silicone based glue such as Goop or E 6000.
Silicone or silicone based glue will stick to almost everything.
If you don't expect the rubber to stretch, many products can be used. -!00% silicone, Gloozit, Seal All and LePage Extreme would all work.
