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 application_number US 12148198 A description referring to fig1 a choke body 10 which is usable in subsea applications is illustrated the choke body 10 accepts an insert 12 inside of insert 12 is bore 14 which communicates through openings 16 to the inlet 18 of the choke body 10 bore 14 communicates to outlet 20 of the choke body 10 an actuator 22 moves plug 24 between the two positions shown in the split view of fig1 in the upper position the openings 16 are exposed allowing the choke to operate to reduce pressure between inlet 18 and outlet 20 in the lower position shown at the top of fig1 the plug 24 covers the opening 16 and there is no flow from inlet 18 to outlet 20 in the choke body 10 in the embodiment of fig1 the choke body 10 further comprises a dog operating mechanism 26 which is also shown in fig6 and 7 a series of dogs 28 extend through openings in a sleeve 30 and are retained by a tab 32 to keep them from being pushed all the way in through sleeve 30 a cam 34 has teeth 36 which mesh with teeth 38 which are in turn rotatable by rotation of shaft 40 shaft 40.
