<p>PROBLEM TO BE SOLVED: To provide a separation prevention device for fluid pipe that can prevent a fluid pipe from damaging as a wedge part of a lock member excessively bites into the fluid pipe and thereby securely maintain a separation preventing function for the fluid pipe even when external force due to an earthquake acts in a direction in which the fluid pipe is separated.SOLUTION: There is provided a separation prevention device 10 for fluid pipe that includes a main body member 11 which is fitted externally onto an outer peripheral surface 2b of a fluid pipe 2 and has a recessed part 12 opposed to the outer peripheral surface 2b, a lock member 15 which is accommodated tiltably in the recessed part 12, and can bite into the outer peripheral surface of the fluid pipe 2, and press parts 13, 14 which are provided at the main body part 11 and press the lock member 15, and prevents the fluid pipe 2 from separating in a pipe-axis direction. The lock member 15 has a plurality of wedge parts 16, 17 in the front-rear direction of the pipe axis of the fluid pipe 2, and includes a projection part 18 which restricts biting of a front wedge part 17 between a plurality of wedge parts 16, 17 into the fluid pipe 2 when the fluid pipe 2 moves to a separation side in the pipe axis direction.</p> |
