Hinkel started his career at Stuttgart before moving on to Sevilla in 2006 and Celtic in 2008. His fourth and final stop saw him feature for Freiburg last season, but he failed to win a new contract.
"I have played at a very high level for 12 years now," he told kicker magazine. "As a result I had no difficulty retiring. At the age of 30, you are on the shelf."
