You should see the hose clip to the right of the pump. Either cut it with side cutters or as Rickard says prize it off.
Remove the rubber mount at the back of the motor then pull it back off the sump at the same time as twisting it in a clockwise direction. Where it connects to the sump it’s just a push fit, nothing to undo.
Fitting the new one is just the reverse, the new pump should come with a replacement clip.
