The youngest British swimmer to compete at the London 2012 Olympic Games – she was 15 at the time – O’Connor (pictured) won six medals at the Glasgow 2014 Commonwealth Games.
She says: “Speedo is the brand I grew up swimming with, so I’m thrilled to have signed with them.
“When you think of swimming, you think of Speedo and I cannot wait to be able to work with them.”
The deal runs until the end of 2016.
