Self-sufficient sequential locking device for injection molding tool

A self-sufficient sequential locking device, comprising:

• an elongate body having two ends which are provided with a first and a second inner engagement element respectively;
• a first and a second outer engagement element selectably engageable with the first and second inner engagement elements respectively for alternatively establishing a first or a second connection by moving the elongate body between a first position in which the first connection is secured and the second connection is simultaneously releasable, and a second position in which the second connection is secured and the first connection is simultaneously releasable;
• and
• a first locking element cooperable with the first inner engagement element for securing the first connection when the elongate body is in the first position and a second locking element cooperable with the second inner engagement element for securing the second connection when the elongate body is in the second position;
• wherein the moving of the elongate body between the first and the second position is mechanically actuated by engagement of the first outer engagement element with the first inner engagement element or the second outer engagement element with the second inner engagement element.
