Abstract
A rotating-lock closure is provided with a traction unit, wherein the closure comprises a housing having a first bearing area for the receiving head of a key to be inserted as well as a second bearing area for the rotating-lock driving support that supports said rotating lock and is mounted so as to be capable of axial and sliding displacement and of rotation in the second bearing area. A shaft having a rounded cross section and extending from the key receiving head protrudes relative to the rotating-lock driving support and has a transverse opening at its protruding end for receiving a pin. A cam track, on which the pin is guided against the force of a spring, is formed by the side of the lock facing away from the housing. The outer periphery of the lock driving support has a non-rounded cross section and is capable, in a passageway also having a non-rounded cross section, of axial and sliding displacement in a first portion or the second bearing area and of limited rotation in a second portion of the second bearing area.
