United initially signed Shrewsbury Town defender Mark Ellis on a one-month loan deal in October 2015.
This became permanent at the start of the January transfer window and he will now be with the club until the summer of 2018.
Ellis started his career with a three-month loan deal at Torquay, from parent club Bolton, which turned into a permanent move in the summer of 2008.
Over 100 appearances and four years followed with the Gulls, which included a short loan spell with Forest Green Rovers in 2009.
He made the move to Crewe in 2012 and became a regular with the Alex through his two-year stay.
He then signed for the Shrews in May 2014 where he helped them back to promotion to League One at the first attempt.
