The invention relates to an expansion anchor with a pin as a first element and with an expansion part arranged on the pin as a second element. One of the two elements has a first web running along the pin, and the other element has a first groove which runs along the pin and into which the first web engages. One of the two elements has a second web running along the pin, and the other element has a second groove which runs along the pin and into which the second web engages. According to the invention, the expansion part is secured to the pin by means of a snap connection, wherein a first latching of the snap connection is formed between the first web and the first groove, and a second latching of the snap connection is formed between the second web and the second groove. The first latching and the second latching hold the expansion part radially on the pin.
