The collar is provided with a coupling groove (16) engaging it from three sides, in which the clamp (17) with a straight-running web locates and with its arms engages from the sides. The U-arms of the clamp evolve from the straight web via a radius into the corresp. groove of the collar (5). Below the collar is arranged a spring body in which claws emerging from the U-arms of the clamp (17) engage. The clamp has two parts which have straight-line sections which are arranged in an outwardly issuing slot in the collar. USE/ADVANTAGE - A spring-elastic clamp for rapid fixture of a chisel used in an extraction machine for mining.
