Latching bolt with a positioning pin which in its end region has a locking pin with which the positioning pin can be moved in a guide bore of a guide sleeve from a locking position protruding axially out of the guide sleeve against the positioning force of an axial compression spring into a retracted neutral position not protruding axially out of the guide sleeve, wherein an extraction knob is provided with an inner mounting sleeve with which the extraction knob is arranged fixedly on a receiving section of the positioning pin in the second end region of the positioning pin, wherein the extraction knob at a radial distance from its inner mounting sleeve forms an outer guide sleeve with which the extraction knob is mounted displaceably on a sleeve section of the guide sleeve and wherein the extraction knob has an unlocking button which is mounted so as to be axially moveable a limited amount in the extraction knob and can be moved from a position protruding axially out of the extraction knob against the spring force of a positioning spring into the extraction knob, wherein the position protruding out of the extraction knob can be fixed by latching means (28, 29, 31, 32, 33) acting between the unlocking button and the sleeve section of the guide sleeve, characterised in that the unlocking button has latching tongues which extend through the upper outer end wall of the extraction knob inwards into the axial region between the inner mounting sleeve and the outer guide sleeve, in that the latching tongues each have a latching groove which lies radially on the outside and faces the guide sleeve in its end region protruding into the extraction knob, in that the latching groove forms an end section of greater radial depth in its end region lying towards the upper outer boundary wall, and an end section of lesser radial depth in its end region lying towards the "lower" end region of the latching tongue, in that a latching ball is inserted into the latching groove, which latching ball is arranged in the region of the upper end section so that it cannot be moved axially when the unlocking button is slid into the extraction knob, and on one side bears on a stop of the extraction knob so that it cannot be moved axially and on the other side bears on the sleeve section slid into the guide sleeve so that it cannot be moved radially and locks the unlocking button axially, in that the extraction knob together with the unlocking button can be moved out of the locking position into the neutral position so that the latching ball passes into a region "above" the upper end edge of the guide sleeve and in this position can be moved radially outwards until it bears on the outer guide sleeve, or so that the latching ball passes into an inner radial recess in the guide sleeve arranged in the region of the upper end edge of the guide sleeve and can be moved radially outwards, in that the latching ball after its radial movement slides into the end region of the latching groove of lesser depth and the unlocking button simultaneously moves into its end position in which it is extracted from the extraction knob and which is defined by the engagement of the latching ball with the end region and the stop of the extraction knob, in that in its locking position in which it is moved radially outwards the latching ball bears on the upper end edge of the sleeve section on the front side and prevents the extraction knob moving back into its locking position.
