Abstract
A dental syringe is disclosed having a head and attached handle. Finger actuated valves in the head control water and air flows to a syringe tip having concentric conduits. A tip retainer assembly includes a holder having a socket to insertably receive the syringe tip. A lock collar, slidably carried by said holder, has a conical surface which acts on ball elements in the holder to urge them into locking engagement with a grooved, inserted portion of the syringe tip. A spring automatically positions the collar to the locking position with movement of the collar in an opposite direction to a tip unlocking position by fingertip pressure applied to the collar.
