Replacement lock for cake pan with lid

This is a model of a lock that seals the lid tight to a cake pan. I dont know which manufacturer made this product, so i cant tell precisely which product this is for unfortunately. The lock is 66,5 mm long and 18,5 mm wide. 

So i bought this cake pan a while ago, so my kids could bring cake to kindergarten/school for birthdays. But after a few uses, the lock that kept the lid sealed to the pan broke, rendering it pretty much useless for its purpose. The only thing i could do (before i learned to make 3D models), was to replace it with a new one, which also broke after a short while. Did i make a replacement model for the new one? Yes i did, and I will upload the model as soon as i can.
