Gloucester have tied hooker Richard Hibbard down to a new deal at Kingsholm.
The Wales international joined from Ospreys in 2014 and has made 56 appearances for the Premiership outfit, including 52 starts.
"I've really enjoyed my time with Gloucester and, once the club approached me about extending my stay, it was an easy decision to make," said the former British and Irish Lion.
"I feel I've improved my game since I arrived. The Aviva Premiership is a tough league, there are no easy games and I think that's actually benefitted me as a player.
"I love playing at Kingsholm, the club and the supporters have been terrific to me and I'm really happy that I'll be staying and playing my part in what we hope will be a successful period in the club's history."
Hibbard won the last of his 38 Wales caps against Ireland in August 2015, and the signing of a new contract with Gloucester could restrict any chance of breaking back into the squad under 'Gatland's Law', which limits the number of players plying their trade outside Wales eligible for selection.
