ABSTRACT:
A device for lifting prefabricated components, particularly made of concrete, or the like, comprising an anchoring element which forms a female seat of a bayonet coupling device and can be embedded in a component proximate to a perimetric side of the component so that the opening for access to the female seat is directed outward, and an engagement element which has a male end of the bayonet coupling device and can be coupled to the female seat. The engagement element, with the male end coupled to the female seat, protrudes from the female seat with a portion which forms an engagement region for lifting equipment.
