A stop device for upper stops and a pull of a Nylon zipper has an upper stop formed by a left stop and a right stop; a pull being installed on one end of a zipper strip. The upper end surfaces and the bottom of the left stop and right stop are formed with protruded stop blocks, and the pull has a left and a right teeth channel, tops or bottoms of a respective teeth channel are formed with stop grooves. When the left stop and right stop enter into the two teeth channels of the pull, the left stop and right stop enter into the stop grooves. Since the stop blocks are resisted against the stop grooves, the left stop and right stop are buckled in the pull. Moreover, the left stop and right stop have the function of preventing the pull from separating from the zipper strips.
