Abstract

A diverless subsea tubular connector with male and female elements that can be remotely connected and disconnected using only axial movement of one of the elements with respect to the other. The connector elements are secured together by a snap spring that prevents their disengagement so long as an axial tension tending to pull them apart is maintained. A release of that axial tension facilitates unlocking the two elements so that they can be pulled apart without requiring hydraulic, manual, or rotational manipulation.
