Abstract: An anti-snag guiding device for a hose, cable or other flexible longitudinal element, designed to prevent such flexible longitudinal element, when laid across a floor or other surface, from becoming trapped or snagged by a wheel of a vehicle or with platform lifts or other types of tools existing in the work place. The anti-snag guiding device incorporates a rigid body made of a single piece of plastic, metal or equivalent material, having a wedge-shaped configuration with a curved profile allowing it to be inserted into the space between the wheel and the floor. The bottom side of the device is flat with a base made of rubber or other elastic material to provide a support element against the floor. The perimeter side surface of the body of the device has a curved-concave cross-section profile against which the flexible longitudinal element rests and slides.
