The present invention relates to an artificial hip joint. It has been proposed in accordance with the invention that the guide pin 5 has an inverted-cone tapered design in order to properly insert the socket insert into the hip socket with a high guide accuracy even under difficult conditions, The diameter of the guide pin 5 at the end of the guide pin 5 is smaller than at the end 8 of the guide pin 5 facing away from the pawl 7.
