Harlequins have announced that fly-half Tim Swiel will return to the club next season on a full-time contract.
Swiel, 21, spent four months on loan with Quins earlier this term before heading back to the Durban-based Sharks in South Africa.
" Tim made a real impact with us on loan earlier in the season and we are delighted that the Sharks have granted him his release to come back to us on a full-time basis," Quins rugby director Conor O'Shea said.
"He is a young player with a huge amount of potential and also someone who showed mentally that he is able to cope with anything thrown at him."
Somerset-born Swiel made 10 appearances during his loan spell, featuring in the European Champions Cup, Aviva Premiership and LV= Cup.
