A propeller includes a hub, blades each provided with a shank, a pivoting connection connecting the shank of the blade and the hub and having a pivot axis and at least one holding system for holding the blade connected to the hub. The holding system is reinforced and includes at least one main stop integral with the hub and configured to be at least partially housed in a transverse groove, provided in a surface integral with the shank of the blade, which extends over at least a part of the circumference of the shank. This solution reduces the risk of blades or blade debris being ejected. An aircraft propulsion assembly includes at least one such propeller.
