Well in tournaments suited connectors aren't as great of hands as they are in cash games. Generally you want to play them if the stacks are deep, like in cash games players often have 100 big blinds in their stacks. In tournaments you'll find that a 30 big blind stack is pretty good.
So you can still play them in tournaments, raising them from the button is still a good idea to steal the blinds or take down the pot with a continuation bet. Also if it's early in the tournament when the blinds are small you can always try to see a cheap flop with them. Remember though that when you're playing these type of hands you're trying to hit a big hand, making one pair is not enough to put a lot of money in with, you're trying to make 2 pair at least or a very big draw.
