The meaning of a collar

[Logic1]

That would work, but I doubt you'd carry a leash all the time.

haha but I am willing to bet that having one rolled up on his belt on a normal day in His bikergear wouldnt be all that strange to him
Heck I wear a pair of thumbcuffs in my keychain all the time

Offering a collar to my girl would mean the same thing as a weddingband. It is a mutual commitment to eachother.
