A pull-turn bolt latch for mounting in an opening in a thin wall, particularly for securing plug-ins, doors or flaps in switch cabinets, comprises a housing that can be secured in a non-round opening in a thin wall, a shaft which is provided with an external thread and which is mounted in the housing so as to be rotatable but fixed with respect to axial displacement, on which external thread a bolt provided with a matching threaded bore hole is guided in the housing so as to be acted upon by pressure by a spring engaging around the shaft such that when the shaft is rotated by hand or by a tool into the stop position at the outer end of the shaft or when the pressure is relaxed the bolt carries out a rotational movement with the shaft covering at least 90°, and in the position remote of the stop position accompanied by axial guidance, such as in an axial slot formed for the bolt in the housing carries out a translational movement in axial direction. The housing has a head part such as a flange which covers the outer edge of the opening in the mounted position, and a body part proceeds from this head part and penetrates the opening. The invention is characterized in that flexible holding elements project from the body part in direction of the outer surface thereof and form a self-locking contact surface or contact line or contact point for supporting the body part without play on the rim or edge of the opening.

1. A pull-turn bolt latch configured to be mountable in an opening in a thin wall, the pull-turn bolt latch comprising: a housing that can be secured in a non-round opening in a thin wall;a shaft which is mounted in the housing so as to be rotatable about a shaft axis, but fixed with respect to axial displacement relative to the housing, the shaft being provided with an external thread; anda bolt on said shaft, where the bolt is acted upon by pressure by a spring engaging around the shaft, and the bolt has a threaded bore hole which matches with the external thread of the shaft;wherein the housing includes: a first stop surface;a second stop surface; anda third stop surface configured to face the second stop surface;wherein the bolt is guided by the housing and the external thread of the shaft so as to have a first movement and a second movement, where: the first movement is a rotational movement covering at least 90° with the shaft where the bolt moves between a first stop position, at which the bolt directly contacts the first stop surface of the housing, and a rotational stop position, at which the bolt directly contacts the second stop surface of the housing, when the shaft is rotated by hand or by a tool; andthe second movement is a translational movement in an axial direction when the bolt is in the rotational stop position, whereby the movement of the bolt in the axial direction is guided by the second and third stop surfaces when the shaft is rotated by hand or by a tool such that the bolt is located between the second and third stop surfaces during the translational movement;wherein said housing has: a head part which covers the outer edge of the opening in the mounted position; anda body part proceeding from said head part and penetrating the opening;wherein flexible holding elements project from the body part in direction of the outer surface thereof and are self-adjustable so as to support the body part without play on the rim or edge of the opening, each holding element being separate from the body part and any other holding element. 2. The latch according to claim 1; wherein the body part has a substantially prism-shaped cross section, and one holding element proceeds from one side of the body part and another holding element proceed from an opposite side of the body part. 3. The latch according to claim 2; wherein said cross section of the body part is rectangular. 4. The latch according to claim 2; wherein a plurality of holding elements are arranged symmetrically with respect to the shaft axis. 5. The latch according to claim 2; wherein two opposing holding elements form a group in each instance; andwherein the group is arranged, respectively, on both sides of the shaft. 6. The latch according to claim 1; wherein the head part forms a handle or finger grip. 7. The latch according to claim 1; wherein a drive for rotating the shaft is mounted in the head part. 8. The latch according to claim 1; wherein the free end of the body part forms at least one projection which serves as a stop for the rotational movement of the turning bolt. 9. The latch according to claim 1; wherein one stop for the rotational movement of the turning bolt is formed by the body part and the other stop is formed by a suitably arranged edge of an opening in a bend or a shoulder of the thin wall. 10. The pull-turn bolt latch according to claim 1; wherein an axially slit sleeve, which is provided with a flange at one end, engages around the spring, the flange having a mark and, for the rest, is held on the head part of the housing so as to be rotatable;wherein the flange of the sleeve supports the spring and the outer end of the shaft against spring force by a rim area facing the spring; andwherein the slot of the sleeve is penetrated by the bolt whose rotational movement is transmitted to the sleeve and therefore to its flange. 11. The pull-turn bolt latch according to claim 10; wherein the mark at the flange of the sleeve is aligned with its slot. 12. The pull-turn bolt latch according to claim 10; wherein the housing likewise has a mark which indicates, in conjunction with the mark at the flange of the sleeve, determined rotational positions of the bolt. 13. The pull-turn bolt latch according to claim 10; wherein the mark on the flange of the sleeve is a notch or a hole; andwherein the mark on the housing is a colored dot that is arranged in such a way that the notch or hole allows the colored dot to be seen in one position of the bolt. 14. The pull-turn bolt latch according to claim 10; wherein the flange of the sleeve forms a projection/recess which cooperates with a recess/projection on the housing for limiting the rotational path. 15. The pull-turn bolt latch according to claim 1; wherein the shaft provided with the external thread has, at its outer end, a head in the form of a screw head with a cross slot or the like tool receptacle, or in the form of a knurled knob, or in the form of a small lever. 16. The pull-turn bolt latch according to claim 1; wherein the body part has a screw fastening instead of flexible holding elements. 17. The pull-turn bolt latch according to claim 1; wherein the body part has a glue fastening or the like instead of flexible holding elements. 18. The latch according to claim 1; wherein the thin wall is formed by a plug-in or a drawer, door, or flap in a switch cabinet. 19. The latch according to claim 1; wherein said holding elements are formed by leaf spring parts which are inserted into the body part. 20. The latch according to claim 1; wherein said holding elements are formed by push elements which are mounted in the body part so as to be displaceable in a defined manner against spring force. 21. The latch according to claim 1; wherein said holding elements are formed by levers which are swivelable in a defined manner at the body part against spring force around an axis extending parallel to the thin wall. 22. The latch according to claim 19; wherein the spring parts are secured by lateral edges of the opening after the housing is mounted in the opening. 23. The latch according to claim 19; wherein the spring parts are formed by the ends of an individual leaf spring that is bent in a U-shape.
