Abstract: A longitudinal adjuster having a release device on a core of an actuating-pull mechanism for use, e.g., on motor vehicles has a connecting eyelet on an end of a housing. An end of the core includes a toothing arrangement which is engageable with a toothing arrangement carried on a retaining pawl in the housing. Normally, the adjuster is maintained in closed condition by a spring acting on the housing and a slide on the housing. The slide can be moved in opposition to the spring to place the adjuster in open condition. In open adjuster condition, the retaining pawl is displaceable such as to disengage the toothing arrangements thus allowing adjustment of a distance between the connecting eyelet and the core end.
