The invention relates to a vessel connector (10) for surgically connecting two vessels and/or prosthetics to each other, comprising a sleeve-shaped body (1), the walls of which are designed to be elastic, such that the force acting on the ligature or suture is limited to the extent that no pressure points or necroses occur in the vessel. It is made of two substantially rigid outer rings (2), delimiting the sleeve-shaped body, and webs (3) present between the rings, wherein at least regions of individual webs have a shape (4) deviating from a straight line over longer distances, and it has at least one ring-shaped region (5) of higher elasticity between the rigid rings. The connector provides a blood-tight connection of at least two natural or artificial vessels, including prosthetic connections, a prosthesis to a natural vessel, or two prostheses to each other. The vessel connection is possible much faster, more easily, and more securely with the novel mechanical connector than using conventional surgical circumferential sutures.
