An explosive powder charge operated setting tool has a housing (1) including an axially extending housing section (5) enclosing a driving piston guide tube (8) axially displaceable within the housing section. The guide tube (8) is held in a neutral position by a spring clip (15, 16). The spring clip (15, 16) is U-shaped and engages at a first end (15a, 16a) radially inwardly of the housing section (5) into a recess (8c, 8d) of the guide tube and bears against a shoulder (8e) at one end of the recess (8c, 8d). The second end (15c, 16c) of the spring clip (15, 16) extends tangentially of and in prestressed contact with an outside surface of the housing section (5) and is diametrically opposite the first end (15a, 16a).
