1. A diffusor for a gas generator of an airbag module, comprising a substantially tubular base body with a longitudinal axis, a baffle cap axially connected to the base body at a first end of the diffusor and a second end of the diffusor opposite to the first end,
wherein in an outer wall of the tubular base body, first and second outflow openings are formed such that gas can flow out of an interior of the diffusor substantially in parallel to the longitudinal axis toward the first and second ends from the diffusor, the baffle cap being free from the first and second outflow openings;
wherein the first outflow opening and the second outflow opening are formed by one single tab which is formed by two parallel notches extending perpendicularly to the longitudinal axis in the outer wall of the tubular base body and by deforming a region therebetween in a radially outward direction, wherein the tab comprises two semidome-shaped elevations.
