    • A safety device for a pressurized beverage container, such as a beer keg, is provided with a locking element (15) formed as a double angled piece with an outwardly tang (22), an oblique segment (23) and an inward projecting tang (24). The tank (22) rests in a trapezoidal recess (29) of a base plate (14) of a rise pipe (8) which in turn includes a conical flare (9) between a lower rise pipe portion of a lesser diameter and an upper larger diameter rise pipe portion (10) received in a housing (2, 7) of the safety device. The conical flare (9) is directed away from the projecting tang (24) of the locking element (15) by a distance larger than the normal opening excursion of the rise pipe (8). This structure allows the assembly of the safety device before insertion into a dispensing aperture (45) of a pressurized keg, as well as the withdrawal therefrom absent injury or damage caused by internal pressurization of the keg contents.
