PROBLEM TO BE SOLVED: To provide a bayonet pipe joint capable of being connected by surely centering a connection tube inserted into a joint body, and having the function of holding the connection tube. SOLUTION: This bayonet pipe joint has a tube butting part 13 for butting an end of the tube to an inner depth part of joint body, a cylindrical guide part 12 having a length to support an outer peripheral surface of the tube, and a packing mount part 14 at an end side, and plural lips 21 and lip packings 20 respectively located at an edge of each lip, and provided with a guide peripheral face 22 larger than an inner diameter of an opening at an end of the packing mount part, and an annular projection part 23 axially projecting, are mounted in the packing mount part. An outer peripheral face of each lip packing is provided with circumferential annular projection 24. A locking ring 30 kept into contact with the annular projection part 23 of the lip packing and a folded inner surface at the end of the packing mount part, is mounted in the packing mount part of the main body. A threaded hole is formed on the packing mount part, a bolt is engaged with the threaded hole, and the holding ring is pressed to an outer surface of the connection tube.
