A cylindrical ring sized to slide over the box end of an oilfield tubular having a given external diameter, has a shoulder at one its ends and a sidewall along its length. The sidewall has a circumferential groove about its interior surface housing a band which can be made tight against the exterior surface of the oilfield tubular by a latch, or other latch means accessible through a slot in the sidewall, and which becomes even tighter if the tubular attempts to escape from the band. In a first orientation, the cylindrical ring is used as a load ring. By turning the cylindrical ring upside down, the cylindrical ring is used as a thread protector for the pin end of the tubular.

La présente invention concerne une bague cylindrique dimensionnée de façon à coulisser sur l'extrémité de boîte de tubage de champ pétrolier possédant un diamètre externe donné, qui possède un épaulement au niveau d'une de ces extrémités et une paroi latérale le long de sa longueur. Cette paroi latérale possède une encoche périphérique autour de sa surface intérieure contenant une bande qui peut être serrée contre la surface extérieure du tubage par un verrou ou par un autre organe de verrouillage accessible à travers une fente présente dans la paroi latérale et, qui devient de plus en plus serré si le tubage tente de s'échapper de la bande. Dans une première orientation, cette baguette cylindrique est utilisée comme bague de charge. En tournant cette baguette cylindrique la tête en bas, on utilise cette bague comme protection du filetage de l'extrémité de tige du tubage.
