Abstract
A device for releasably interconnecting a head part to a handle part of a dental handpiece characterized by one of the two parts having a catch element in the form of radially projecting catch nose coacting with a counter element in the form of a recess disposed on the other part and a resilient sleeve-shaped member, which forms an outer generated surface of one of said head and handle parts, acting on one of the elements to urge the pair of elements in a coupled state and allowing a disengagement of the elements to enable releasing the connection between the hand parts when a squeezing pressure is applied to the sleeve shaped member.
