Abstract: A protector assembly for covering a pin of a threaded pipe and a method for assembling such a protector assembly. The protector assembly comprises a cover, a retainer and at least one fastener for fastening the retainer to the cover. The cover includes a tubular portion defining a longitudinal axis from a closed end to an open end, the open end defining a rim for axial abutment with the retainer. The retainer has an abutment face for abutment with the rim. The rim comprises a bore extending therethrough. A fastener extends through the bore of the rim and engages the retainer, the fastener extending substantially in parallel with the longitudinal axis and exposed on the cover side of the bore of the rim for engagement by a tool or user to operate the fastener.
