A B S T R A C T A coupling with a latching mechanism for holding a nipple inserted into the coupling member in its connected position by engaging with a shoulder surface of the nipple; a safety locking mechanism in the coupling member includes a locking member that is in its operable position before the latching mechanism releases the nipple so that the shoulder surface is securely pressed against the locking member by the back pressure in the line until the back pressure decreases to a safe level; the latching mechanism and safety locking mechanism thereby include each a spring of such strength that the spring of the latching mechanism will overcome the spring of the safety locking mechanism when the back pressure has substantially decreased so as to automatically release the nipple for complete disengagement.
