摘要： A gas burner for caravans, boats and vehicles in general includes an injector holder to be applied at an opening in a cooktop of a caravan, boat and/or vehicle in general and having an injector connected to a gas inlet; a burner cap resting on the injector holder and having a vertical conduit facing the injector at the bottom and leading, at the top, into a distribution chamber of the fuel mixture to generate a flame ring; and a cover resting on the burner cap and delimiting at the top the distribution chamber of the fuel mixture. At least two protruding pins are provided at the bottom surface of the cover and can be inserted into corresponding through holes in the burner cap to snappingly engage elastic coupling members coupled to the injector holder.
