According to a preferred embodiment the barrier comprises a bar means and a pair of attaching means, typically clamps, connected at the two ends of the bar means. A C-type clamp may be employed to connect the bar means to a U-shaped support or a two plate clamp means may be used to attach the bar to the point where two U-shaped struts converge in a T. The attaching means can also comprise a shackle type clamp for attachment to rounded objects or it may be a pointed tip suitable for attachment to a surface having receiving holes therein.
