A non-lethal projectile comprises a rear portion in the form of a cylinder (2) coupled to at least two symmetrical petal-like impact elements (1) which are capable of opening upon leaving a bore and are designed to form, in a closed configuration, a cylinder having an outside diameter equal to the diameter of the cylindrical rear portion and also having an axial cylindrical opening which transitions into an axial opening in the cylindrical rear portion of the projectile. The petal-like elements have an asymmetrical cross section and an inner conical groove, the base of which is disposed at the rear portion-end of the projectile, wherein, in the front portion, each petal-like element has a unidirectional relief.
