A resilient pipe thread protector comprises a substantially annular resilient body having an interior opening provided with a thread pattern conformed to mate with the threads of the ends of a drill pipe. To allow for installation onto drill pipes of various sizes the thread protector includes a convolved split defining a plurality of interlocking projections and includes a similarly patterned circular spring within the interior thereof. The foregoing assembly may be formed by injection molding with the convolved split being achieved through the use of a separator plate splitting the mold. In the alternative the convolved split may be formed along inclined surfaces where each projection is received in a pocket-like recess conformed for telescopic receipt thereof.
