Abstract
Abstract A pair of flexible nonelastic straps made of a plastics material are connected by an intermediate nonelastic strap to form a band adapted to extend around the nape of the neck in engagement with it. The nonelastic straps extend across the outer sides of a pair of ear covers and are provided with longitudinal slots receiving headed bosses projecting centrally from the ear covers. The ends of the band are provided with means for connecting them to the bottom of a safety hat in front of the ears when the hat is worn on the head, whereby the band will hold the ear covers in place over the ears.
