A drill pipe and casing protector comprises an annular body having two pieces with identical edges. A first edge includes at least two opposing formations longitudinally formed thereon whereby when one piece is inverted with respect to the either piece, the first edges mate to form a pivotable connection allowing the body to be opened and closed about a pipe. The second edges of each piece include opposing interlocks which form an aperture along the second edge when the body is closed. The aperture receives a locking pin to retain the body in a closed position around a drill pipe as well as around a bushing assembly. |
