head 42 and is adapted to receive a removable weight 44 which can be hollow or solid connection system 10 is not limited to any one location within the body of club head 42 and there can be multiple connection systems 10 integrated within a single club head 42 placing removable weights in different locations within the club head allows golfers to adjust the trajectory of their shots by changing the center of gravity and the moment of inertia for example placing a heavy removable weight toward the bottom and rear of the club head moves the center of gravity in the same direction permitting the golfer to hit a ball with a higher launch angle this also increases the moment of inertia increasing the size of the sweet spot and minimizing the chances that an off center hit will result in a poor shot similar to fig2 and 2 a teeth 16 bite into the side of removable weight 44 once it has been inserted to prevent removal without release tool 24 similar to previous embodiments in order to remove the removable weight 44 the release tool 24 is pushed against release collar 22 to disengage teeth 16 from contact with weight 44 another embodiment of the present invention is similar to the embodiment shown in fig1 2 2 a and 3 except that connection system 10 is separate from and is removably disposed within a hosel or insertion hole of the golf club head not integrated with the walls of the hosel or insertion hole in this embodiment a plurality of teeth may be disposed on the outside of frame 14 to connect connection system 10 to the inside of the hosel.
