An intraoral anti-snoring device, for shifting the lower jaw forward in relation to the upper jaw, with an upper jaw bar and a lower jaw bar that are both U-shaped and are connected to each other in a hinge joint at their outer flanks facing away from each other via protrusion ties by means of fixing buttons. At each of the two end sections of the protrusion tie, a round hole is provided for accepting the fixing button. The invention proposes a curved design for the protrusion tie, specifically an S-shaped design, with the center section having a cross-sectional contour—at least in part—that permits a temporary change of the distance of the round holes relative to each other by means of an elastic deformation of the protrusion tie in the longitudinal and in transverse direction. Preferably, the center section has an elongated hole that extends from one round hole to the other round hole and has a width that is smaller than or equal to the diameter of the round hole. Due to the resulting longitudinal edge strips that are capable of spring action, the fixing button is able to avoid excessive pressure by moving into the elongated hole.
