PROBLEM TO BE SOLVED: To provide a coming-off preventive connecting structure between a fiber reinforced resin pipe and a socket capable of performing a high coming- off preventive function, in piping using the fiber reinforced resin pipe under internal water pressure. SOLUTION: This is a coming-off preventive connecting structure between a fiber reinforced resin pipe 2 and a socket 11, wherein an end portion of the fiber reinforced pipe 2 is connected to the socket 11 equipped with a breakaway preventing ring 3 in a recess groove 111 formed on an inner surface of the socket 11. An outer layer 21 made of a thermoplastic resin is provided on an outer surface of the end portion of the fiber reinforced resin pipe 2. When coming-off force acts on the fiber reinforced resin pipe 2, a locking portion 3b of the breakaway preventing ting 3 can be locked to the outer layer 21.
