LEGO Part Hinge Plate 1 x 2 Locking with 1 Finger on End without Bottom Groove

It’s hard to describe this clip.  It is a 1×2 grey plate, with a little end that things can clip on to.  But it’s not the average LEGO connection, instead I call it a finger joint, and this would be the male end of it.  I’ve seen this used as a side view mirror on the Speed Champions sets, As a clip to hold up lamp posts and other signs, and as a clip on Star Wars sets to allow for moving wings and hatches.  It is new and unused.
