Burstner 726G swinging shower/toilet partion door latch

[Reboot]

I am trying to find a source for this latch or a better method to lock back the partion?
Having just returned from a West country trip to find the shower partion swinging around because the plastic latch has become weak and given up on doing its job of holding the door in place.
I did find it a weak point in the clever method of sharing the shower and toilet area but now its become a PTA to find a replacement.
Any idea where I can find a replacement or a better method of locking back the shower/sink partion?

Hi, I’ve just bought a 2016 Nexxo 690 with exactly the same arrangement. I intend to improve this arrangement to make it more secure. I’ll let you know what I come up with

 

[Reboot]

Hi, After I had removed the plastic shower liner I found that the original latch wasnt fixed to the plywall very well. The fixing screws where only screwed in by a few millimeters which had come adrift so it was then only held by the plastic shower wall which flexed and allowed the partion door to swing free. I replaced the screws with longer ones and then added a white metal sash security window latch(bought from a local widow/door supplier) at the top above the orginal plastic latch to double secure the partion door.
This double latch system hasnt let me down so far.
