Annotated close-up of wiper arm latch behind the splines, shown…

To remove a wiper arm, lift it away from the glass and slide the latch up to hold the arm. Then pull the arm & its base straight off the splined shaft.

To install, slide the arm onto the splined shaft, lift the wiper away from the glass, push the latch down, and lower the arm onto the glass. Check the arm's position & wipe range, and remove to re-position if necessary.
