Abstract: A module separation mechanism, in particular for rockets, includes a cylindrical first body, a cylindrical second body, and a ring connecting the two bodies, The ring comprises at least one tension lock together with a cover. The first body comprises at least one radially mounted actuator that is adapted to eject the tension lock together with the cover from the ring in a manner to disengage the ring. The first body further comprises at least one ejecting member adapted to eject the second body from the first body. The outer surface of the ring together with the cover is faced with the outer surface of the first body and the second body.
