I just bought a Kata backpack, MiniBee-110 PL. It has an enormously long waist strap that I think is removable. It's attached to the bag by this connector (in the picture below), but I haven't been able to manipulate it so it snaps open. Before I get too aggressive and break something I thought I would ask the question: Can someone recommend a solution for operating this connector (or if it's even possible to open it)?

Update Thanks to the suggestion here is the result showing the opened connector. It did require quite a bit of pressure:
