Abstract
The present invention is directed at a quick release connection system to facilitate customization of golf clubs. It can be used to interchange shafts, removable weights, or soleplates quickly and easily. Teeth are disposed on the inside of a frame so that a shaft may be inserted with minimal resistance, but cannot be removed without specific steps which may require the use of a simple tool. Strengthening and interlock devices are provided to ensure performance quality akin to traditional golf clubs.
