Eheim AEH7444450 Ez Clip

There are 4 clips in a aquarium filter Eheim Professionel. I have broken two of the four clips.
The clip has a barcode UPC 720686742956 and it's full name is "Eheim AEH7444450 Ez Clip 2226/27/28/29 Designed for Aquarium". The original one is made of ABS (see a picture, it has a label "ABS").
I decided to slightly change a model. It is thicker than the original and has no an useless hole.
