Abstract

A fastening member provided at the end of a spring-elastic mounting strap of a tire chain. The fastening member has an introduction passage and an attachment passage for a cooperating fastening member that is secured to the other end of the mounting strap. A guide passage interconnects the introduction passage and the attachment passage. This guide passage, at the level of a hook arm portion that partially separates the introduction passage from the attachment passage, extends at an angle of greater than 90.degree. relative to the longitudinal axis of the attachment passage. In this way, the cooperating fastening member can be easily hooked in the fastening member. The inclined course of the guide passage relative to the longitudinal axis of the attachment passage assures a high degree of protection against accidental unhooking.
