sounds to me that the breaker is coupled to another breaker using the "tie-bar" This is essentially a plastic or metal clip that joins two single pole breakers to form a double or two pole breaker. By using a tie bar it also tells me that the circuits the breaker feeds is probably a multi wire circuit, as in a three wire red, black and white circuit. the white is the common return for the two circuits. You'll have to buy an exact duplicate of the one you are removing to be able to include it under the tie bar.
