Similar to my wall mount but takes a 32ish mm belt.
It is not a "clip" - the belt is fully captive.

This mount fits my power case - S2s without the case won't fit. Other makes of the case may or may not work.

I used it in earnest today and it worked very well. The phone sits a little higher than it did using the leather belt clip case and the new position is better when pedalling a bike.

The corners can be a it sharp so I've done beltthing2 with them rounded. It slices OK but I haven't printed it.
