Onguard Bulldog Combination Standard U-Lock
I have had same problem twice. The end cap fell off in about 30 minutes and could not retrieve. Started jamming also to where I did not trust locking it.

Onguard Bulldog Combination Standard U-Lock
A total piece of garbage. After the first two weeks the cap at the end of the lock fell off. Not a big deal, but an indication of workmanship. After another two weeks the lock began jamming either in the locked or unlocked position. After fighting to get the lock open open after the fourth jam I gave up and threw it away. A complete waste of money. Buy something else.
