A snow anti-skid device a plurality of which are to be fitted at intervals around a motor vehicle wheel. Each device is in the form of a horseshoe-shaped strip-form yoke or stirrup comprised of a thickened central yoke section with curved limbs (20) for embracing the tire (15) extending away from opposite sides thereof. The free ends of the limbs are in the form of claws provided with magnets which engage under and adhere to the shoulders of the wheel rim. The thickened central region of the yoke may be provided with a coating of a resilient material, which can be molded on so as to extend through openings in the strip and provide a non-slip surface abutting the tread of the tire and a studded surface for engaging the ground. One or both limbs of the yoke or stirrup may be resiliently longitudinally extensible, or may be adapted for positive adjustment of its length.

An anti-skid device for mounting on a wheel comprised of a wheel rim and a tire, said device comprising: a yoke having a central section for engaging the tread face of said tire; a pair of limb means, one each extending outwardly from each of the opposite ends of said central section, each of said limb means being arcuately bendable and having a free end; and magnetic attachment means secured to each of said free ends for engaging the shoulder of said wheel rim so that when said device is mounted on said wheel, said limb means yield to forces acting in the radially inward direction upon said central section of said yoke in order to not transmit said force to said magnetic attachment means, at least one of said attachment means including a magnetic claw means having a portion which extends beyond the width of said limb means so that when a force acts upon said central section in a substantially circumferential direction, the width of said at least one magnetic claw means acts against said wheel rim to prevent tilting of said yoke to preserve the placement of said device upon said wheel. An anti-skid device for mounting on a wheel comprised of a wheel rim and a tire, said device comprising: a yoke having a central section for engaging the tread face of said tire; a pair of limb means, one each extending outwardly from each of the opposite ends of said central section, each of said limb means being arcuately bendable and having a free end; and magnetic attachment means secured to each of said free ends for engaging the shoulder of said wheel rim, so that when said device is mounted on said wheel, said limb means yield to forces acting in the radially inward direction upon said central section of said yoke in order to not transmit said force to said magnetic attachment means, at least one of said attachment means comprises a claw element having two, spaced apart plates of a magnetizable material with at least one elongated magnet disposed therebetween so that its poles lie on opposite plates, said plates extending parallel to the plane of the yoke, so that when a force acts upon said central section in a substantially circumferential direction, the width of said at least one claw element securely grips said wheel rim at spaced apart locations to preserve the placement of said device upon said wheel.
