Clarke was released by the Yellows earlier this week, having made 42 appearances for the club since his debut in November 2020.
He has been plagued by two serious injuries over recent seasons but is now returning to full fitness after missing the opening months of the 2022/23 season.
Clarke joins a Bucks side currently 11th in the Pitching In NPL West Division, eight points adrift of the top five.
The versatile left-sided player could make his debut against league leaders Macclesfield on Saturday afternoon.
