Abstract: A pipe thread protector device for protecting the threads at the end of a casing section or the like, and including an elastomeric shoe having a cavity or recess in one side thereof for receiving the threaded end of the casing, and further having an elongated generally cylindrical constriction sleeve made of braided or interwoven wire elements connected to the shoe. One end of the constriction sleeve is embedded in this shoe and the other carries a plurality of tensioning tongues. The constriction sleeve construction causes it to undergo a reduction in diameter when it is placed in tension, and an enlargement in diameter when placed in compression.
