Propeller for an aircraft engine comprising: a blade mounting associated with each blade, mounted so as to pivot on the hub according to an incident pitch axis; a pivoting link between each blade mounting and the root, allowing the blade to pivot relative to the blade mounting thereof according to a blade collapsing axis; associated with at least one of the blades, a member for controlling the collapsing/extension of the blade configured to pivot the root relative to the blade mounting according to the collapsing axis; and a passive device for synchronising the collapsing/extension of the blades, including a central synchronisation element mounted so as to rotate relative to the hub according to the propeller rotation axis, as well as a coupling element associated with each blade, including a first end mounted on the blade root and a second end mounted on the central synchronisation element.
