Abstract

The present invention relates to a mounting arrangement for fastening a shaft in a locking device, the mounting arrangement ( 1 ) comprising—a shaft ( 2 ) for insertion into a handle follower of a locking device; —a locking member ( 33 ) for fixating the shaft after insertion to prevent undesired removal from the handle follower, and—a release member ( 32 ) for releasing the locking member to enable desired removal of the shaft from the handle follower, wherein the locking member ( 33 ) is movable between a locking position for fixating the shaft in the handle follower and a release position, and wherein the release member ( 32 ) is operatively connected to the locking member for moving the locking member from the locking position to the release position. The invention also relates to a locking device ( 10 ) comprising such a mounting arrangement ( 1 ).
