A technique for securing drilling riser joints in a drilling riser string is presented. The drilling riser joints have a tubular housing that has a box configuration on one end and a pin configuration on the other end. The drilling riser string is assembled by connecting the pin end of one drilling riser joint to the box end of an adjoining drilling riser joint. A moveable ring is used to connect adjoining drilling riser joints. The moveable ring is used to drive a fastener, such as a dog, of one drilling riser joint against the adjoining drilling riser joint. The moveable ring is driven axially from a first position, where the fastener is not engaged against the adjoining drilling riser joint, to a second position where the fastener is engaged against the adjoining drilling riser joint. A latch is used to prevent the moveable ring from moving inadvertently from the second position. This prevents the drilling riser joints from disconnecting inadvertently.
