A doubling-up fitting includes a clamp element with a clamp base and at least two clamp arms rising from the clamp base at its ends. The free clamp ends are angled inward and extend over the clamp base. A rotatably mounted spreading disc is arranged between the clamp base and the free clamp ends. A disc opening leads into a recess in the spreading disc where the diameter is greater than the disc opening diameter. A plurality of outer contour portions spread the free clamp ends radially outward less far in an initial rotational position of the spreading disc than in a final rotational position. An adjusting disc arranged in the recess of the spreading disc has a thread. The outer diameter of the adjusting disc is smaller than the diameter of the recess in the spreading disc and larger than the opening diameter of the disc opening.

A retractable lock for doors is provided that includes a frame mountable on the front side of the door panel for receiving a retractable lever grip. The lever grip is moveable along a release path between a retracted position inside the frame, where it is secured by a locking device, and an actuating position outside the frame. Further rotation of the lever grip along an actuating path transmits into rotational movement of a pinion which drives a locking rod, which is longitudinally slidably guided at the inner side of the door panel by engagement of outer teeth of the pinion at cutouts of the rod.
