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.

An assembly for enhancing vehicle traction comprising: a wheel having two sides, connection means for facilitating attachment of the wheel to a vehicle, and bearing surface means for supporting the wheel on an underlying surface; cross chain means for increasing traction between the bearing surface

An assembly for enhancing vehicle traction comprising: a wheel having two sides, connection means for facilitating attachment of the wheel to a vehicle, and bearing surface means for supporting the wheel on an underlying surface; cross chain means for increasing traction between the bearing surface and the underlying surface, including first coupling means for connecting one end of the chain means to one side of the wheel and second coupling means for connecting a second end of the chain means to the other side of the wheel; and the first coupling means including: a lug defining a key, having a bottom surface mounted on the wheel, and having a tongue vertically spaced from the lug bottom surface and the wheel, and the tongue being directed away from the bearing surface, and a socket member connected to the one end of the cross chain means, having a keyway conforming to the shape of the key and a thickness which allows the socket member to be slidably moved to a retaining position between the tongue and the wheel from a vertically aligned position of the key and keyway so as to retain the socket member relative to the wheel. In a wheel having first and second sides, a periphery and operable to be supported on an underlying surface, an improved means for attaching traction enhancing chains to the wheel comprising: a plurality of lugs circumferentially spaced around one side of the wheel, each lug being on a common radius and including a tongue spaced from the wheel and extending away from the periphery; a corresponding plurality of radially extending slots circumferentially spaced around the wheel at a common radius, operable to retain one end of a cross chain; and a corresponding plurality of retainer plates, each plate covering a portion of the corresponding slot and being mounted to the wheel by a spring hinge having sufficient resilience to hold the plate against the wheel when the slot is located above the wheel center.
