joining two shapes together, need help???

I've draw a perfect circle with elipse tool and i've made a line coming off that circle, i've then draw another line symetrical from it and joined them to form a rectangle joined to a circle.
Now how the hell do i get rid of the join where the rectangle meets the circle? there are only four paths on the circle and i cant make the rectangle 'become one' with it???
