A connection for oilfield use is disclosed. It features male and female components held together by dogs actuable through one of the members and into the other. Different configurations of the connections envision a built-in preload to the connection when made-up. This is accomplished by a cantilevered component at the extremity of one of the components of the connection. Alternatively, the preload feature can be incorporated into the dog or other locking assembly that holds the components of the connection together. The connection is particularly useful in subsea chokes which have a removable insert which can be mounted to or removed from the choke body which is located subsea.
