DEFINITION

Classification: 439/675

Having annular, push-pull-engaging contact concentrically disposed about longitudinal axis of engagement:

(under subclass 660) Coupling part intended to be coupled to its mating coupling part solely by linearly pushing the one coupling part directly toward and into engagement with the mating coupling part, and the coupling part is separated from its mating coupling part solely by linearly pulling the said one coupling part away from the other coupling part in the direction opposite to the direction of the engaging motion; and wherein at least one of the contacts of the coupling part is in the form of a cylindrically-shaped tube, sleeve, or shell or in form of a circularly-shaped ring, and the axis around which the contact is cylindrically or circularly disposed is coincident with the longitudinal axis along which the coupling part engages its mating coupling part.
