ABSTRACT:
Polarizing and locking means for a pair of mateable units including a member having a key on one unit and a member having a plurality of keyways on the other unit. A ring-shaped element selectively obstructs all the keyways but one on the associated member and the key is angularly disposed on the other member to register with the unobstructed keyway when mating the units. One of the members is moved axially and rotated to engage the key with the rear wall between the keyways for locking the units together.
