Abstract: The invention relates to a latch lock (1) for a tool (2) used in the injection moulding of plastics or the die-casting of metals having a moving element (A) such as a mould plate or similar intended, after having been displaced for a certain distance, to be locked in the attained position prior to any subsequent actuation. According to the invention, an axially slotted sleeve (3) is so arranged as to accommodate internally a connecting piece (4) exhibiting radially projecting drawing wings (5) that are attached to a tool plate (B) and are movably guided by the slots (6, 7) in the sleeve along the sleeve (3). An end closure (9) attached to a tool plate (A) is also detachably attached to the guiding slotted sleeve (3).
