A coupling bolt (19) is mounted so as to be axially displaceable to a limited extent in at least one of the centring bodies (20) of the injection mould. The coupling bolt (19) projects out of the locked injection mould at the back under the pressure of a pretensioned spring (24). It has an annular shoulder (19f') in a section projecting beyond the end of the centring body (20). By virtue of the annular shoulder (19f'), a steel spring washer (25), under spring pretension, is pressed radially into an annular groove (29) of the sliding guide bush (18). This steel spring washer (25) can be released for unlocking spring-back into its starting position by means of a relative movement between the coupling bolt (19) and centring body (20). It is thus achieved that, with a removal of the injection mould half receiving the centring body (20) from the associated mould carrier (26) a mutual locking and, during mounting of this injection mould half on the mould carrier (26), an unlocking take place, in each case automatically. <IMAGE>
