Crumby intruder glued bondage article? (7)

I believe the answer is:

sandman

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 sandman that I've seen before include "Sender to sleep of children" , "Who could send you to sleep" , "sleepy character?" , "One of the Beach Boys" , "Imaginary person who causes children to sleep" .)

I've seen this clue in the Sydney Morning Herald.
