Abstract: A snow chain assembly having a pair of cross-chains is connected with a wheel assembly by a pair of connecting devices. One connecting device includes a lug mounted to the inside of the wheel and a cooperating socket plate that receives the lug and is secured thereby. The second connecting device includes a T-shaped radial slot and a T-shaped pin connected to the chain. When the pin is inserted in the slot and moved radially outward, the slot prevents disengagement of the pin. Spring biased retaining members may be attached to the wheel as locks to further prevent chain disengagement.
