ABSTRACT:
A tubular stabbing protector includes: a plurality of body sections together forming a first opening and a second opening, the first opening sized to be secured over a pin end of an oilfield tubular and the second opening sized to fit over a connection to which the pin end of the tubular is to be engaged and opening away from the first opening; and a releasable lock between each adjacent body section of the plurality of body sections, the releasable lock being automatically releasable when the second opening is fit over the connection to permit the plurality of body sections to separate sufficiently to release the pin end.
