<p>A self-locking hook for supporting a load on a support surface is disclos ed. The hook has a relatively rigid C-shaped body which includes a surface d efining an opening for accommodating a support component and a connector hav ing a load bearing or attachment point. The surface of the opening includes a first contact area and a second contact area. The load bearing or attachme nt point is attached to the body relative to the opening such that applicati on of a load at the load bearing point w hile the first contact area is cont acting a component rotates the body about the first contact area until the s econd contact area abuts the component. This self-locking feature allows the hook to be used effectively on component surfaces which are at almost any a ngle or slope relative to horizontal.</p>
