An apparatus for orienting members and for maintaining their rotary alignment during orienting members. The apparatus comprises first and second cylindrical elements, a rotation prevention element, a collar and a retainer. Each element has an outside wall, and first and second ends, each end having an outside edge. The first element has portions defining a first plurality of notches located at the outside edge of its first end. An external threaded portion is on the outside wall of the first element and next to the first plurality of notches. The second element has portions defining a second plurality of notches located at the outside edge of its first end. The first plurality has a different number than the second plurality. The first ends of the first and second tubes have substantially the same outside diameter and are abutted during connection so that a cavity is formed whenever first and second tube notches substantially overlap. A rotation prevention element is placed in the cavity to prevent rotation of the first and second elements. A collar with an internal threaded portion is slidably disposed about the second element. The internal threaded portion engages the external threaded portion of the first element to connect the elements. A lip connected to the collar prevents separation of the collar from the second element.
