1. An automatic locking safety needle cover that is configured to connect with a syringe, the needle cover comprising:
a housing having a longitudinal axis and a resiliently deflectable axial lock;
a needle connected with the housing, the needle having a distal tip; and
a sleeve configured to be telescopically received in the housing and to resiliently deflect the axial lock, the sleeve having a longitudinal axis, an unlocked extended position, a retracted position, and a locked extended position, wherein:
in the unlocked extended position, the sleeve covers the distal tip of the needle and the resiliently deflectable axial lock is in a deenergized state;
in the retracted position, the distal tip of the needle is exposed;
in the locked extended position, the sleeve covers the distal tip of the needle, the sleeve is blocked from moving to the retracted position by the axial lock, and the longitudinal axis of the sleeve is parallel to the longitudinal axis of the housing; and
the sleeve resiliently deflects the axial lock during movement of the sleeve from the retracted position to the locked extended position and not during movement of the sleeve from the unlocked extended position to the retracted position; and
the sleeve rotates relative to the housing during movement of the sleeve from the unlocked extended position to the retracted position.
