Abstract: In an anti-skid device in which anti-skid bodies are connected to be arranged in the circumferential direction of a tire of a car, connecting/separating workability is simplified. Connecting components are also simplified in their structure and production. Rod-like and tube-like connecting components are attached to the front-side and the rear-side of each anti-skid body. A manipulation member is configured such that an attaching rod and a connecting rod arranged in parallel with each other are connected by a manipulation rod, the attaching rod and the connecting rod are inserted into attaching holes and connecting holes of the tube-like connecting component, and the manipulation member is thus movable in the crossing direction of the tube-like connecting component. An elastic member is provided which applies a backward movement force to the manipulation member.
