Zusammenfassung:	The utility model relates to a pipe line via hole protecting piece which comprises a pipe body of a hollow structure. An outer sealing ring is arranged on the pipe body. The left side of the outer sealing ring is an outward extending portion. The right side of the outer sealing ring is a pipe penetrating portion. The outward extending portion is provided with a first inverted tooth region. The pipe penetrating portion is provided with a second inverted tooth region and a third inverted tooth region. The tooth direction of the first inverted tooth region and the tooth direction of the second inverted tooth region face the outer sealing ring. The tooth direction of the third inverted tooth region is the same as the tooth direction of the second inverted tooth region. The section, between the third inverted tooth region and the second inverted tooth region, of the pipe body is an empty tooth section. The pipe line via hole protecting piece can be firmly clamped on a piece where a via hole needs to be formed, the in-house line can be protected for a long time, and assembling is easy in the construction process.
