A bit of duct tape fixed on the corner of charger, a household implement (7)

I believe the answer is:

adaptor

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for adaptor that I've seen before include "Connector (O, not E)" , "Tap road (anag)" , "Kind of electric plug" , "Electrical connector" , "It enables fit" .)

I've seen this clue in The Hindu.
