Yes, those are the exact connectors. That one is very similar to the normal trailing socket on a standard French or Belgian extension cable , with the lip around the outlet to stop moisture getting in.

A salamander I believe is the term in English for a heavy-duty type of grill, where the food is placed on a wire rack and is heated by IR reflected from the elements both above and below. The elements in ours are the silica glass-encased type which reach operating temperature very quickly. They are also available fired by gas. You can find pictures of them on the websites of catering suppliers, such as

although that one is "only" 3kw [Linked Image] The very good commercial gas ones deliver the heat eqivalence of about 6kw.

It is a curious name, probably back to the legend that salamanders are supposed to be able to live inside a burning fire or some stuff like that. Nonsense really.
