The 2 RAM - bars come in a stable double plastic packaging. This has only been clipped to my great joy! (Photo 1) It is easy to open without scissors and without destruction. Latches themselves are still eingeglipst in an extra mount. (Photo 2) Grasp the bracket with both hands and on one side, turn the plastic packaging down / press. Thus, the latch is released and it can be removed without problems. I had just put on disposable gloves for assembly. The RAM is detected immediately and done since his service.
On picture 2, the already developed RAM - bolt from the iMac to see 27 "5K.
