- 9. The plug as claimed in claim 8, wherein:
- said second projecting portion is disposed further from said two elastic pieces than said first projecting portion.
- 10. The plug as claimed in claim 9, wherein:
- said second projecting portion has an outer rim portion, said outer rim portion being angled such that a front edge of said outer rim portion has a smaller diameter than a rear edge of said outer rim portion.
- 11. The plug as claimed in claim 10, wherein:
- a retaining member of said automobile cigarette lighter socket is received in said securing recess of said front cover.
- 12. The plug as claimed in claim 1, wherein:
- said first projecting portion has a larger diameter than said second projecting portion,
- said second projecting portion is disposed further from said two elastic pieces than said first projecting portion, and said second projecting cover has an outer rim portion, said outer rim portion being angled such that a front edge of said outer rim portion has a smaller diameter than a rear edge of said outer rim portion.
- 13. The plug as claimed in claim 10, wherein:
- a retaining member of said automobile cigarette lighter socket is received in said securing recess of said front cover.
- 14. The plug as claimed in claim 1, wherein:
- said first projecting portion has a larger diameter than said second projecting portion,
- said second projecting portion is disposed further from said two elastic pieces than said first projecting portion, and said second projecting cover has an outer rim portion, said outer rim portion being angled such that a front edge of said outer rim portion has a smaller diameter than a rear edge of said outer rim portion.
