"I am really happy to sign a new contract and stay at the Ospreys for the next couple of seasons," said Jones.
"I feel there's a healthy competition here with a lot of quality in the front row and it helps to get the best out of each other and that's shown with how well our scrum in particular has been going this season.
"I feel I have really developed my game here over the last few seasons, especially with someone like Duncan Jones on the staff at the Ospreys.
"Being able to tap into his experience and knowledge has been important for my development as a player. I will play anywhere for the team but being allowed to focus on one role has been important for me."
Jones underwent shoulder surgery at the beginning of December and is progressing well under a rehabilitation programme designed by Ospreys medical and fitness teams. He is targeting a return for pre-season.
"Prior to my injury I felt I was playing my best rugby and picking up momentum and enjoying playing regularly for the Ospreys," said Jones.
"I'm currently working hard to get back to full fitness with the top quality physios and conditioning team we have here.
"Injuries are always frustrating and being out now, in particular, is frustrating because you want to help the boys out and lend a hand.
"We are having a tough time regarding injuries and results but there is the talent and experience in this squad to change all that."
