The invention relates to a device for producing an ETS anastomosis connection and/or a STS anastomosis connection, comprising a ring (10) with two pins (11). Each pin has a free end (12) and a fixed end (13) which is secured to the ring the pins extending, viewed from the fixed end toward the free end, next to and set apart from each other in the same direction. The pins each have a clamping section where the pin extends, in a first position, parallel to and along said ring from a first side of the ring to a second side of the ring that is situated diametrically opposite said first side in order to be able to clamp tissue of the wall of the receiving vessel between the ring and the clamping sections. The clamping sections of the pins are, in a second position, at an angle with respect to the plane defined by the ring in order to form, together with the ring, a jaw which widens, viewed in the direction from the fixed ends toward the free ends. The pins are swivellable, with respect to the ring, by means of a swivelling movement from the second position to the first position for closing the jaw.
