The 19-year-old Wales U19s international has started all of Wolves U23 Premier League 2 games so far this season and he was also a key member of the squad who reached the play-offs in the previous campaign.
After growing up in Chasetown, Leak joined Wolves from a young age - he will now link up with the TNS who play in the Welsh Premier League.
We wish the central defender well for his loan spell as he aims to pick up a sustained run of first team experience.
