Definitions

• the invention relates to a stapling device with a lower part carrying an anvil plate, a clip magazine on a bearing block of the lower part which can be pivoted about a transverse axis in the direction of the anvil plate against the force of a return spring preferably about the same transverse axis as the clip magazine on the bearing block of the lower part, pivotable in the direction of the clip magazine against the force of a return spring, a clip part which can be inserted into an ejection channel of the clip magazine and a cover cap which engages over the top part from the top .

• a modified embodiment variant of the invention provides that the cover cap in the intermediate region between the driver and the bearing block is mounted so that it can be tilted to both sides by means of a bearing pin which engages in a locking recess in the upper part.
• the bearing pin can be designed as a spring element so that it automatically locks with the upper part.
• the spring preload of the cover cap is achieved in that it is held in the working position between the bearing journal and the bearing block by a spring which is supported on the upper part and is preferably designed as a conical spring.
