Harlequins director of rugby Conor O'Shea has committed his future to the club by signing a new contract.
The former Ireland international has been joined by head coach John Kingston and skills coach Collin Osborne in penning a deal until the end of the 2013-14 season.
"This is an exciting time to be part of Harlequins," he told the club's official website. "Our talented squad is developing in the right direction and I cannot thank the players, coaching team and support staff enough for how they have made my role so enjoyable.
"Our aim is to continue to develop and play the game in the way we believe it should be and to bring the success to the supporters that they deserve.
"It is also important to recognise the great contribution made by John and Collin over the years. Since my arrival at Quins, I've benefitted from the exceptional legacy that they, along with Tony and others have helped to create, and we are looking forward to continuing to work together over the coming seasons."
O'Shea took over the role in March 2010.
