The invention relates to a tool, especially a screwing tool having a handle with a chuck, and a blade, especially a screwdriver blade, that can be inserted into an insertion opening of the chuck. The blade inserted into the insertion opening is held by a detent of the chuck, said detent being displaced from a detent position to a release position by actuating a trigger. The inventive tool is characterized in that the detent comprises a detent projection which is located on a spring arm that extends in the axial direction of the insertion opening and on the periphery thereof. Said spring arm is displaced by a control element of the trigger that can be displaced in the axial direction from the detent position to the release position. The insertion opening is configured by an insertion cylinder located in a cavity of the handle. The insertion cylinder is produced from plastic and the spring arm is associated with the insertion cylinder in order to form a single part consisting of the same material.

What is claimed is: 1. A tool, comprising a handle with a chuck, a blade which can be plugged into a plug-in opening of the chuck, the blade removably plugged into the plug-in opening by being retained by a catch of the chuck, the catch has a latching protrusion which is disposed on a spring arm, the spring arm extending in the axial direction of the plug-in opening and along the periphery of the opening, and the latching protrusion is displaced from the latching position into the release position by a control element of an axially displaceable trigger; and the control element is an axial extension of an annular body which has a through-opening for the blade and is associated with the end side of the handle. 2. The tool according to claim 1, characterized in that the plug-in opening is formed by a plug-in sleeve disposed in a cavity of the handle. 3. The tool according to claim 1, characterized in that a plug-in sleeve is produced from plastics material and the spring arm is associated integrally with the plug-in sleeve. 4. The tool according to claim 1, characterized in that the spring arm has a slope which interacts with the control element. 5. The tool according to claim 1, characterized in that the control element is an axial extension of an annular body which, having a through-opening for the blade, is associated with an end side of the handle. 6. The tool according to claim 1, characterized in that an annular body has retaining arms which project into a retaining passageway of the plug-in sleeve. 7. The tool according to claim 1, characterized in that a radially outwardly oriented passageway wall is formed by a handle cavity. 8. The tool according to claim 1, characterized in that an annular body is forced into a forward position by the force of the spring arm. 9. The tool according to claim 1, characterized in that the latching protrusion engages a recess of the blade. 10. The tool according to claim 1, characterized in that the blade has a plastics-material sheath which incorporates a recess. 11. The tool according to claim 1, characterized by a latching recess disposed in annular form in a plastics-material sheath. 12. The tool according to claim 1, characterized in that an annular body consists of plastics material. 13. The tool according to claim 1, characterized by a collar which is associated with the blade and, in the plugged-in state, is located in front of an annular body. 14. The tool according to claim 1, characterized by an O-ring located between a collar and an end side of an annular body. 15. The tool according to claim 1, wherein the handle, the chuck, the trigger, and a plug-in sleeve consist exclusively of an insulating material.
