The invention relates to an inserter for an infusion set for intermittent or continuous administration of a therapeutical substance, such as e.g. insulin. The inserter comprises a needle hub comprising an insertion needle and two spring units assuring automatic insertion and automatic retraction of the insertion needle. The inserter comprises a housing ( 1 ), a carrier body ( 2 ) carrying an infusion part ( 8 ), a needle hub ( 3 ), a first moving unit ( 4 ) bringing the carrier body ( 2 ) to a forward position and a second moving unit ( 5 ) bringing the carrier body ( 2 ) to a retracted position. The inserter is characterized in that it has means for activation which should be activated at least once in order to bring the carrier body ( 2 ) from a retracted to a forward position, and back from the forward to the retracted position.
