Hammer glue! Bombenfest!

I have in the past for patching of diving equipment (eg glove of torn by excessive pulling on tightening) used him. Also there was already that the material anywhere else can possibly go wrong again, the splice itself is however hard to come apart!
The advantage is the flexibility of the adhesive in the dry state. So he can not break even under stress.

Last is from my sports watch (Garmin Forerunner 405CX) rubber (?) - Torn bracelet. Now that's a challenge, because the bonding surface is very narrow and the daily load up! Normal adhesive can be as easy times totally forgotten. Even when Stormsure I was very skeptical despite positive experience from the past. I have provided the two ends with adhesive, fixed in a special device from the craft supplies (rather fiddly to get the two ends exactly together without them diverge flutschen), then again glued around it and let it dry for 12 hours. And indeed: The bracelet holds! I took advantage of it now again a few days and have already dragged off by force. The splice will not crack! It's almost as if the rubber had been sealed again.
Admittedly Despite Nachfeilen gross Klebereste the clock gains so no beauty contest. But it holds and that was for me the most important thing.
