another funny one, plugged in an obd2 connector - cant get it back out

[roadwarrior]

i bought an obd2 gismo for my 2016 sprinter based autosleeper winchcombe, now i cant get it out, i heard a "click" as i pushed it in, is there a button or lever i need to press to get it out ?

Device type? Photo?

sorted, a firmer pull was needed as it has a robust clip on the obd gismo - but thought i would check before a further jiggle
