Which connector type is described as having a coupling ring that slides along the axis to mate or unmate?

• A. Push-Pull coupling
• B. Bayonet coupling
• C. Screw coupling
• D. Quick disconnect

Answer: (A)

Push-Pull coupling uses a coupling sleeve or ring that slides along the axis to mate or unmate. The action is linear: you push the connector in to engage the pins and sockets, and you pull the sleeve back to disconnect. This design allows fast, one-handed mating and reliable release without twisting or threading, which is why the axial sliding of the coupling ring is the defining behavior. Bayonet couplings require turning or twisting to lock the lugs into place, not sliding the ring along the axis. Screw couplings rely on threading to mate, which involves rotating to engage. Quick disconnects use a release mechanism to separate, but the primary action is not the axial sliding of a collar to mate or unmate.
