ABSTRACT:
This connector comprises a bar shaped frame part and a U-shaped frame part that fits over and is slidable relatively one to another on the bar shaped parts. One frame part has in it a slot that extends lengthwise therein and has ratchet teeth that extend into the slot and the other part carries a pin that can engage with the teeth like a pawl to lock the two parts against relative movement in one direction. The two frame parts are connected with each other by elastic rubber tension members which yieldingly urge the frame parts toward a retracted position. Non-skid tire chains equipped with these connectors can be applied to tires without jacking up the wheels and the connectors will tighten the chains and hold them tight as soon as the wheel begins to move. Also, we disclose a non-skid assembly having traction pads of flat pliable material and provided on their outer surfaces with knobs and cups to resist skids.
