What's it called, sprung cable retaining P clip?

[Nick]

I'm after some spring steel P clips. The type that have barbs on the wings which will grip the web of an I or U section beam. These for use on an old lorry in restoration. Don't want to drill holes in chassis unless absolutely necessary. Web thickness is about 1/2", cable dia. about 3/8". Have goggled for ages but am struggling. Any idea what they are called? Many thanks, Nick.

I called them 'knock on girder cable clips'.
