A fluid pipe connection device includes a plug sleeve fixedly fastened and mounted on a pipe joint used for mounting an internal tooth snap ring and a push tooth ring in the pipe joint and the plug sleeve. The internal tooth snap ring clamps the pipe wall after the pipe passes through the plug sleeve, the push tooth ring and the internal tooth snap ring. The push tooth ring pushes away internal teeth along the pipe insertion direction so as to lead the internal tooth snap ring to release the pipe wall before disassembling a pipe. A top end of the push tooth ring is basically flush with an exposed element or contracted in the exposed element under the pipe connection state. The exposed element is the more prominent one of the plug sleeve and the pipe joint. Also provided is a pipe disassembly tool.
