The new deal will keep the 20-year-old at White Hart Lane until the summer of 2019.
Winks told the club’s official website: “I’m delighted. I’ll just continue focusing on my football, try to kick on and try to get into the squad.
“I train every day with the players, I do exactly the same programme as them and I’m on the same schedule.
“Naturally, I’d love more minutes but I do believe the training and the hard work I’m putting in means I’m playing my part every day.”
“I’ve definitely progressed and I feel I’ve come a long way since the start of the season,” added Winks.
“I’ve learned a lot from the manager, from the players and everyone around the club.
“I’m really enjoying my time, loving it. I just want to take that next step now and that’s to play a few more minutes and generally kick on.”
