Bicycle chain tip. The chain breaker tool is the one tool that will pay for itself. Chains break off at times for no apparent reason. Keep it with you when biking, as it can also help another stranded cyclist.
chains that come loose that fast , and is not a cause of a weak bar bolt slipping , for sure is caused by improper oiling of chain and its overheating , heat makes metal expand so chain goes slack if it gets hot
It is not an overly difficult repair so you should not have much problem with it even if it is your first time using the tool.

You need specialized workshop tools to break a chain, and another tool to rejoin it (Chain Breaker, Chain Joiner). These are quite expensive items and costs more than a few new chains each, so it is probably more cost effective to get a new chain. It is odd the current chain has stretched that much. perhaps it had one too many links to begin with?

They sure do look like bicycle chains, but without measuring the links with a micrometer and comparing them with a bicycle chain, i wouldn't be comfortable installing one you made based off of eyeballing it alone. You may know this already, but be sure to remove both sprockets the certain chain rides on, and assembling the 3 pieces as one assembly back on the shafts, its much easier then loosening the shafts from the main unit.
