The versatile attacker initially joined the Seadogs in October and has made four appearances since moving to the North Yorkshire coast.
Vincent had been in productive form for Leeds United’s Under-21s before the temporary switch. He featured 13 times for Scott Gardner’s side this season, scoring twice and providing five assists.
The move gives him further exposure to senior football after he had already gained experience against older opposition in the EFL Trophy and National League Cup.
Vincent can operate as a winger or at full-back, offering Scarborough another option as they look to benefit from his attacking contribution and versatility.
Leeds confirmed the extension on November 13, adding that the club will continue to monitor his progress during his time with the Seadogs.
