Disclosed is a device for anastomosis of a tubular structure comprising afirst and a secondmembers of a generally hollow open configuration which each includes a rigidpart and anelastic part, and a connection member for interlocking the first and secondmembers. Eachelastic part is configured to be arranged circumferentially of each rigidpart, respectively,such that anastomosis is obtained, in use, at a contact area in-between theelastic parts.
