ABSTRACT:
An improved quick connector substantially simplifies string make-up by eliminating the need for a perfect longitudinal alignment between adjacent sections before engagement. An elongated recess in either the pin or box connector permits the pin to be inserted into the box at an angle. Interaction between the recess face and a surface on the opposite connector causes the pin to automatically align with the box. When the pin reaches its fully engaged position in the box, a spring tension snap lock ring having multiple annular teeth meshes with complementary grooves to lock the pin and box together.
