There is disclosed an improved device for locking reciprocating piston type fluid actuators in a desired position. The device includes a body, a piston having a lost motion connection to the body, a locking piston being movable with respect to the piston, an actuating cone supported on the piston, split locking cone elements surrounding the actuating cone and having a connection to the body, a split locking ring interconnected to the lock piston and surrounding the split locking cone elements, a housing containing the elements, a movable rod extending into the housing for engagement by said body, and means to supply fluid under pressure to the locking assembly, the application of pressure initially moving the locking assembly and when the rod is in its desired position for locking and further movement provides wedging locking of the structure in its housing bore and locks said rod in position.
