In a swing door for barriers in passageway systems (1), the overload protection (14) consists of a supporting part (15) fixedly connected to the pivoting part (4), of an abutment (19) located on the drive shaft (9) and of at least one catch element (18) which is mounted under prestress between the abutment (19) and the supporting part (15). The arrangement of the abutment (19) on the drive shaft (9) prevents damage to the drive shaft (9) as a result of frequent use of the overload protection (14). <IMAGE>
