A connector device for attachment to an object in connector holes formed near a surface of the object for lifting the object comprising:
- a connector rod having a first end for insertion into one of the object connector holes;
- said connector rod having an axis;
- a lifting bolt with a lower end adapted to engage the object surface and an upper end for attachment to a lifting mechanism for lifting the object;
- said lifting bolt having an axis;
- said lower end of said lifting bolt being movable into contact with the object surface to exert a clamping force, in conjunction with said connector rod, on the object;
- a base assembly having a lower member with a socket therein for receipt of said connector rod and an upper member extending transversely to said lower member and having a socket therein for receiving said lifting bolt wherein the lifting bolt axis and the axis of the connector rod extend transverse to one another;
- and
- a lock mechanism mounted on said lifting bolt, said lock mechanism being movable to a locked position preventing movement of said lifting bolt relative to said upper member.
