Thermostat housing leak!!

Ive noticed a leak the other day near the thermostat housing,
the garage replaced the seal that holds the stat and replaced the coolant but its still leaking.
water pump is working also could this be due to a air lock ?

is this a common prob for these to leak stat housing / the 3 hoses
now im thinking that the clips that hold the pipes on are knakered the (non jubilee type)

also had the heating on to try out dont suppose that might be burning coolant??
Engine 1.8 clipper g plate

the flanges can warp, so woth trying a new one. is it deffo the flange thats leaking and not the waterpump itself?

Alrite John,
Ive taken to garage to sort.
thinking might be split in pipe whilst cold no leek but as soon as the engine warms to normal temp so to speak then the leak starts think it may be leaking from the small pipe and droping on to the large pipe below hard to see though cause its leaking from the rear.

Also noticed this morn that the pass side steering rack gaitor has split just to add more expense lol.

been told that the thermo housing has warped is this a common prob.
