The 21-year-old has previously spent time at Maidenhead United, Braintree Town, Dagenham & Redbridge and Stevenage.
Having made seven senior appearances for the Bees, including four this season, the academy graduate will now go out on loan once more in order to find regular playing time.
Clarke, who can also play at full-back, will return to Griffin Park in January.
