Catch lever for a discharge device of a firearm, in particular an automatic firearm, having a closing device and a securing device (40; 140), wherein the catch lever - is able to be moved between a locking position locking the closing device and a position which does not lock the closing device, and - has a securing element (101; 201; 301) which - is able to be moved relative to the catch lever between a release position and a securing position, - assumes its release position when the closing device engages with the catch lever, if the returning closing device exerts an adjusting effect on the securing element (101; 201; 301) in the backwards direction, and does not engage with the securing device (40; 140) in the release position, even if this simultaneously assumes its securing position, and the catch lever is able to be brought into its non-locking position, - and/or assumes its securing position when the closing device runs onto the catch lever, if the closing device exerts an adjusting effect on the securing element (101; 201; 301) in the forwards direction, and engages with the securing device (40; 140) in the securing position, if this simultaneously assumes its securing position, and sets the catch lever itself in its locking position, wherein the closing device simultaneously engages with a sear formed on the catch lever. - is able to be moved between a locking position locking the closing device and a position which does not lock the closing device, and - has a securing element (101; 201; 301) which - is able to be moved relative to the catch lever between a release position and a securing position, - assumes its release position when the closing device engages with the catch lever, if the returning closing device exerts an adjusting effect on the securing element (101; 201; 301) in the backwards direction, and does not engage with the securing device (40; 140) in the release position, even if this simultaneously assumes its securing position, and the catch lever is able to be brought into its non-locking position, - and/or assumes its securing position when the closing device runs onto the catch lever, if the closing device exerts an adjusting effect on the securing element (101; 201; 301) in the forwards direction, and engages with the securing device (40; 140) in the securing position, if this simultaneously assumes its securing position, and sets the catch lever itself in its locking position, wherein the closing device simultaneously engages with a sear formed on the catch lever. - is able to be moved relative to the catch lever between a release position and a securing position, - assumes its release position when the closing device engages with the catch lever, if the returning closing device exerts an adjusting effect on the securing element (101; 201; 301) in the backwards direction, and does not engage with the securing device (40; 140) in the release position, even if this simultaneously assumes its securing position, and the catch lever is able to be brought into its non-locking position, - and/or assumes its securing position when the closing device runs onto the catch lever, if the closing device exerts an adjusting effect on the securing element (101; 201; 301) in the forwards direction, and engages with the securing device (40; 140) in the securing position, if this simultaneously assumes its securing position, and sets the catch lever itself in its locking position, wherein the closing device simultaneously engages with a sear formed on the catch lever.
