Abstract: A connecting device for connecting a table leg to a table leaf having a back-gripping element, which can be disposed on the table leaf and has an engagement hole and a locking device, which can be disposed on the table leg. The locking device has a clamping element having an engagement hook which is designed to engage the engagement hole of the back-gripping element, a spring element, which is supported at least indirectly against the clamping element and at least indirectly against a spring abutment, and an actuating element. The actuating element acts on the spring abutment so that, in a locking position, the spring abutment applies sufficient force to secure the engagement hook of the clamping element in the engagement hole, and in an unlocking position, the spring abutment is in a position in which the spring element is at least partially unloaded in relation to the locking position.
