The invention provides a connector and a tail part sealing attachment thereof. The tail part sealing attachment comprises a tail sleeve and a sealing pat, wherein a back end opening for allowing the sealing part to be mounted in the tail sleeve from back to front is formed in the tail sleeve; a stop structure for preventing the sealing part from moving forwards is also arranged in the tail sleeve; the tail part sealing attachment also comprises a blocking part which is mounted at the back end of the tail sleeve and used for preventing the sealing part mounted in the tail sleeve from being separated from the back end of the tail sleeve; a threading hole for allowing a cable to pass through from front to back is formed in the blocking part; and a pushing inclined plane which is matched with the tail end of the sealing part in a pushing manner when the sealing part moves backwards to enable the tail end of the sealing part to be retracted radially so as to tightly wrap the cable is also arranged on the front side of the blocking part. According to the tail part sealing attachment, after the sealing part is mounted in the tail sleeve from the back end opening, the sealing part in the tail sleeve can be prevented from being separated from the back end opening due to the blocking part, so that it is ensured that the internal parts in the tail part are not separated from the tail sleeve in the mounting process of the tail part sealing attachment; and in addition, the parts are simple in structure, and quite convenient to install.
