A pluggable and unpluggable device and a handle for the same are provided. The pluggable and unpluggable device includes a carrier, a shaft disposed at the carrier, and a handle movably mounted on the shaft and adapted to engage with and pull out, from an apparatus, the pluggable and unpluggable device in an engaged state and a pulled-out state respectively, alternately and repeatedly. The handle includes a handle body, a guide tunnel disposed in the handle body, and an engaging portion disposed on the handle body. The handle body fits around the shaft by the guide tunnel to thereby slide or rotate relative to the shaft. The engaging portion engages with and escapes from the apparatus as the handle body slides relative to the shaft by the guide tunnel. Therefore, the handle is unlikely to sever, capable of being locked and unlocked, one-piece and thus structurally simple, and space-efficient.
