Abstract
A simple, direct stem fixing device of minimal weight and material. The stem fixing device utilizes an expansion nut and a fixing bolt which connects the expansion unit to the stem. The fixing bolt connects to the stem by a mount set within the lower portion of the vertical tube, thereby minimizing the necessary length and weight of the fixing bolt. Alternate embodiments of this invention also allow the upper end of the vertical tube to be permanently closed, and provide a separating bolt to free the expansion nuts from its tightened position.
