A pivot connection system includes an elongated member having a generally ball-shaped end. A rigid socket is sized to receive the ball-shaped end. The rigid socket has a first opening into which the ball-shaped end is inserted and a second opening. The ball-shaped end has a width greater than the width of the first opening. The ball-shaped end has a deformable hollow core. A core lock is sized to be received within the core to prevent the core from deforming after the ball-shaped end is inserted into the socket.
