Beschreibung
Zusammenfassung:	Apparatus for coupling first and second tubular members includes a first ring coupled to the first tubular member and having a castellated annular first surface with teeth extending in a first direction, and having a projecting tab extending in a second direction opposite the first. The tab is received in a recess in the first tubular member and has a beveled surface. A key is configured to be disposed in the first recess, and has a beveled surface that engages the beveled surface of the tab. A through-bore in the key is aligned with a fastener-receiving bore in the first tubular member and a fastener is disposed in the aligned bores. A second castellated annular surface coupled to the second tubular member has teeth meshing with the teeth of the first castellated annual surface.
