An attachment device for attaching a sling to a hoist by engaging with an attachment formation on the hoist comprises first and second elements disposed in face to face relationship with one another and moveable relative to one another between first and second positions. The first element comprises a slot having a first portion through which the head of an attachment formation will pass and a second portion extending from the first portion and through which the body of the attachment portion can pass but through which the head will not pass. The second element has an opening through which the head of the attachment formation can pass and which aligns with the first portion of the slot in the first element when the first and second elements are in their first relative position and which aligns with the second portion of the slot when the first and second elements are in their second relative position, in which position the second element blocks the first portion of the slot in the first element.
