Example implementations relate to an optical connector assembly apparatus. For example, an optical connector assembly apparatus can include a lead-in nose disposed at a proximal end of the apparatus for insertion into a sleeve housing, where the sleeve housing has a shutter flap to cover an opening in the sleeve. Also, the optical connector assembly apparatus can include a plurality of beams transverse to the lead-in nose to provide a force to hold the shutter flap in an open position, and a tab disposed at a distal end of the apparatus to receive an end cap of an optical blind-mate connector adapter.
