Claims17
A coupling for connecting two vacuum cleaner hoses comprising:
- (a) a first open end;
- (b) an elongated columnar body that is rigid and maintains substantially planer external surface orientation, said body portion encompassing an inner cavity;
- (c) a second open end;
- said coupling forming an airtight seal when connected to vacuum cleaner hoses at each of said first and second open ends.
