This patent describes an anti-rotational, tubular joint for connecting sections of conduits together. The joint consists of a pin member having male threads adapted to be affixed to an end of a section of conduit; a box member having female threads adapted to be affixed to an end of another section of conduit. The female threads cooperate with the male threads to form a connection when the pin member is rotated in a first direction with respect to the box member; a lock sleeve slidably positioned on the box member and movable longitudinally between an unlocked position and a locked position when the pin member is threaded in the box member, the sleeve having longitudinal grooves extending along an upper portion thereby defining resilient fingers; ratchet teeth on each of the fingers; and ratchet teeth on the pin member adapted to cooperate with the ratchet teeth on the fingers when the sleeve is in the locked position to allow rotational movement between the lock sleeve and the pin member in a first direction while preventing rotational movement between the lock sleeve and the pin member in an opposite direction; and means on the lock sleeve and the box member for allowing longitudinal movement while preventing rotational movement.
