How I have to call this?
In Spanish is called "encastre plástico", how is called in English?
When you get a product screw and you try to open it you will find the "encastre plástico" that still locking the product. It is a small piece of plastic that is often found it when a product is disarmed and it is located in the edge of the product body. Its function is lock a side with the other.
I didn't find the way to add a picture so my description be more clear.
I hope you understand me and I will also apreciate if you correct me any mistake that I may have done in my description.
