Disclosed is an easily detachable snow chain conveniently installed on a wheel of a vehicle without having to move the wheel. According to an embodiment of the present invention, the easily detachable snow chain, which is detachably mounted on a tire, comprises: a main slippage preventing device; a first binding line; a pair of auxiliary slippage preventing devices; and a second binding line. The main slippage preventing device covers the tire to maintain a frictional force against a road surface. The first binding line is formed using a single line to be fastened by a coupling device to allow the main slippage preventing device to be in close contact with the tire while maintaining an equal interval. The auxiliary slippage preventing devices are arranged on both the left and right sides of the main slippage preventing device and allow the snow chain to be interlinked due to an elastic restoring force and the load of the vehicle when the tire is moved in a progressing direction. The second binding line is used to bind the snow chain by the coupling device to allow an interval between the auxiliary slippage preventing devices to be uniformly maintained and to not allow the snow chain to deviate toward a lateral side of the tire.
