identification of electronic components?

I have a small in car heater that had a cheap cigarette lighter plug attached to it due to bad connections inside said plug the unit overheated .My question is on taking the unit apart to replace it there are two small electronic components one is a brown glass like elongated blob with three evenly spaced red rings around it (I think it is a resistor or similar) the other is clear light green plastic with what looks like a fuse arrangement inside it is 5 mm high and 2.5 mm across .These were attached across the negative and positive terminals of the plug.My question is what are they and in what order should they be connected + to - or - to + or can I discard them completely .I am going to connect the heater directly to the battery via a fused connector do I need these extra components or can they be discarded.Also does anybody know where I can purchase the said items once I have identified them.Thanks in advance for any help.
