Use a screwdriver to lever the open end of the outer plate off the pin, then slide it away from the other pin and the link will come apart. Replace it by pushing the plate with the two pins through the links, push the plate with two holes over the pins, then put the clip closed end on one pin, and spring the other open end over the other pin. Just make sure when you put it back that the closed end of the clip is pointing in the direction the chain will go when you are pedalling
Think of it as a fish swimming against the current
