Formerly with ChromaSport & Trophies United Counties League Premier Division side St Andrews, Hickey joined Boro from Barwell in the summer and made seventeen appearances for the club, including thirteen starts.
He scored one goal against Leamington and contributed two assists before being loaned back to Barwell for a period of three months.
With that loan spell coming to an end, the attacking midfielder has now been transferred back to Kirkby Road on a permanent deal.
