A guide and/or setting device (400) for elements (404), in particular fastener elements comprises a hollow guide piece (440), a plunger (420) axially displaceably arranged within the guide piece (440), and holding members (462) which are displaceably guided perpendicular to the plunger and have holding noses (489) at their ends associated with the end face of the plunger. In a retracted loading position of the plunger, a respective element can be inserted from the side between the holding noses (489) and the free end face of the plunger (420) and the holding noses (489) can subsequently be moved laterally outwardly during an advance movement of the plunger (420) under the action of the latter, in order to release the element (404). The holding members (462) are biased in the direction towards the longitudinal axis (436) of the plunger (420) or of the guide piece (440) and have respective control surfaces (490) above the holding noses (489) which cooperate with control surfaces (421) provided on the plunger and can be moved outwardly to the side against the bias force until the respective element (404) can be moved under the action of the plunger (420) in the axial direction past the holding noses.The holding members or fingers are mounted to the plunger and hold an element until at least the point when the element is in place between the work piece before the holding members or fingers release the element. Clamping means (495) biased in the direction towards the longitudinal axis are provided beneath the holding noses and exert a clamping action on the element (404) while it is pushed by the plunger (420) past this clamping means.
