One-armed bow cleat?

What is this sort of cleat called, which Phil Bolger often included on his designs? It's basically a big canted one-armed cleat with a metal cross pin obviously intended for mooring and towing loads.

​

 

Is this the one?

Yes, that's the one, but I think it's supposed to be used so that the strain goes on the hook and not directly on the pin. And what is it called?

 

It's called a thumb cleat.

 

Thanks, but I have never seen a "thumb cleat" with a cross pin like that, only the small ones for looping the sheet around or something like that.

 

I like it.

thumb bitt or bollard
horizontal bitt or bollard
lay down bitt or bollard

A livestock brand number or letter on its side is called lazy. E.g. 2 followed by a horizontal 2 followed by P would be; 2 lazy 2 P.
Hence:
lazy bitt or bollard

 

philSweet is correct, it is a thumb cleat.
The cross bar is common, the "thumb" part gives friction to resist the sheet pulling out of your hands and the cross bar gives a fast/easy secure that can be quickly released.
Ones without cross bars served the same purpose, but were generally used on little boats for racing where one person would work/play the jib sheets in more-or-less constant manner.
Ones with cross bars were also commonly used on small boat halyards, with the halyard around the thumb you would 'sweat up" the halyard and then secure it.
