Abstract: In a connection device for coupling a load to a lifting lug (2) by means of a support bolt (6) which is located so as to be able to be rotated in a through-opening (15) of a ring holder (4), which has a threaded shaft (8) and a bolt head (7) which protrudes radially beyond it and which can also be rotated therewith relative to the lifting lug (2) with a coupled load (10), the ring holder (4) is covered at the lower side thereof by an end flange (12) at the lower end of a sleeve (11) which is releasably secured to the support bolt (6) by means of tension in an axial direction. There is provided on the ring holder (4) at least one locking member (18) for the bolt head (7) which blocks the bolt head (7) in terms of rotation in a locking position and which is not in engagement with the bolt head (7) in an initial position.

Abstract: A ring nut. A suspension ring includes a base having a sleeve with a threaded bore that is rotatably mounted in a penetration opening. The sleeve is supported by a circumferential annular collar at a bearing surface, surrounding the penetration opening, that is on an exterior at the end of the sleeve facing away from the underside of the base with a non-rotationally symmetrical head profile. The sleeve protrudes at the lower end into a central opening of a disc resting against the underside of the base and is connected thereto in a rotationally fixed manner but does not project at the underside from the disc. A locking member on the base can be brought into a locking position, cooperating with the head profile for locking in the rotational direction, and into a neutral position where the head profile is released in the direction of rotation.

Abstract: An eye bolt, comprising a lifting eye and a supporting bolt, wherein the supporting bolt sits, rotatable, in an insertion opening of the lifting eye and comprises, a threaded shaft and a bolt head. The supporting bolt protrudes radially from the lifting eye and is supported by an underside of the lifting eye, on a bearing surface formed on the lifting eye and running around the insertion opening. The eye bolt further comprises at least one locking member which can be brought into engagement with the bolt head and by means of which, in a locking position of same, the bolt head can be rotationally blocked vis-à-vis the lifting eye. The at least one locking member is further attached to the lifting eye radially next to the bolt head and is secured there, wherein the at least one locking member can be brought into a starting position, in which it is not engaged with the bolt head, and also into the locking position rotationally blocking the supporting bolt relative to the lifting eye.

Abstract: The invention relates to a ring nut (1) comprising a suspension ring (2) which forms a base part (2A) in its lower area, in which a sleeve (4) with a threaded bore (6) open to the underside of the base part (2A) is rotatably mounted in a penetration opening (3). The sleeve (4) is supported by means of a circumferential annular collar (7) thereon at a bearing surface (8) of the sleeve, surrounding the penetration opening (3), on the base part (2A), and is provided on the exterior at the end region of the sleeve facing away from the underside of the base part (2A) with a non-rotationally symmetrical head profile (5). The sleeve (4) protrudes at the lower end region thereof into a central opening (21) of a disc (20) resting against the underside of the base part (2A) and is connected thereto in a rotationally fixed manner but does not project at its underside from the disc.
