Everything with arming the door at departure was fine.  No issues with arming the door.  Upon arrival; the girt bar was extremely difficult to place into the door bracket.  When I was finally able to get it into the J-clips; I noticed that the bracket was too far to the left and would have caught on the fwd side of the aircraft door when opened by catering.  I bent down and re-positioned the girt bar onto the J-clip; which was extremely difficult. It seems that the plastic collars on the girt bar need to be adjusted; the plastic collar on the right side is butted up against the slide flap; which makes it extremely difficult to place the girt into the clip.  I asked the CA to look at it and explained my concern.  He took the girt bar out of the J-clips and then placed the girt bar back into the J-clips; and also found it difficult to do so.Have Maintenance check the collars on the girt bar.
