PROBLEM TO BE SOLVED: To provide a structure of a joint hook for a tire anti-skid device that is capable of effectively preventing a fork-shaped joint hook from disengaging from an engagement hole formed at a joint of an anti-skid net body while a vehicle is running. SOLUTION: Means 13 of resistance to engagement holes 12a, 12b are formed at leading-edge fold-back portions 11x, 11x of joint hooks 11a, 11b which are forked and bent into a U shape in the cross section. Various types of resistance means 13 are made available. In one example of the resistance means 13, a wedge-shaped protrusion 14a with a diameter larger than a bar diameter d is formed on the inside of the leading-edge fold-back portions 11x, 11x of the joint hooks 11a, 11b.
