Abstract: The present invention is directed to a split locking ring for wellhead components. In one illustrative embodiment, the device comprises a first internally threaded wellhead component, a second wellhead component, at least a portion of which is positioned within an opening in the first wellhead component, and a rotatable split lock ring comprised of at least two externally threaded sections, wherein at least a portion of the sections of the split lock ring are positioned between the first and second wellhead components and rotated to threadingly couple the sections of the split lock ring to the first wellhead component and thereby secure the second wellhead component to the first wellhead component.

Abstract: The present invention is directed to various embodiments of a connector. In one illustrative embodiment, the connector comprises a first component, the first component adapted to be coupled to a second component, an outer collar positioned around the first component, the outer collar adapted to be threadingly coupled to the second component, and a plurality of collet fingers positioned between the outer collar and the first component, the outer collar having a surface that is adapted to engage the collet fingers and urge the collet fingers into engagement with the first and second components when the outer collar is threadingly coupled to the second component. The present invention is also directed to various methods of coupling a first component to a second component.
