Claim:
An anchor system for a hollow wall or ceiling comprising: an anchor portion having a flange and a penetrating portion extending from a rear surface of the flange, the penetration portion having a fixed sleeve extending from the rear surface of the flange and a pivoting locking leg connected to the fixed sleeve by a hinge, the fixed sleeve having a non-round opening extending longitudinally therethrough, the pivoting locking leg having a stub extending from a rear surface thereof to retain the penetrating portion rigid as the anchor is inserted into the wall or ceiling; and a pin portion having a body including a flexible shaft, the pin having an actuating element extending transversely from the shaft, the shaft tapering, near the actuating element toward the actuating element and defining a transverse dimension, the actuating element having a heel at about a rear surface thereof, wherein when the pin is inserted into the opening, the actuating portion contacts the stub to separate the pivoting locking leg from the fixed sleeve portion and to pivot the pivoting locking leg portion toward an inner surface of the wall or ceiling, and wherein rotating the pin engages the actuating element at the heel with the stub to lock the leg in place, the shaft flexing to accommodate rotation of the leg more than or less than 90 degrees to secure the leg against the inner surface.
