Abstract
A locking tubing system includes a length of tubing lying in any geometric complexity including a substantially straight line and a first fitting body having a securing member rotationally locked thereto. The first fitting body is affixed to one end of the length of tubing. The system also includes a first nut having a plurality of openings in cooperative relation to engage the securing member, a second fitting body having a securing member rotationally locked thereto, the second fitting body is affixed to the other end of the length of tubing and a second nut having a plurality of openings in cooperative relation to engage the securing member. The first nut and the second nut are threaded onto corresponding mated fittings, each securing member being engaged with at least one of the openings of the respective nuts thereby locking each of the nuts to the respective fitting body.
