A securing and arming device (10) has an operating body (20). Prior to an arming time, this operating body (20) is secured in a position of rest on a support device (12), namely by means of a securing element (30), which here is in a securing position. If the securing element (30) is moved into a release position, it releases the operating body (20) to make a movement in relation to the support device (12). After the arming time, the trigger body (20) is in an operating position by means of a rotating movement in relation to the support device (12). A delay element (22) is designed to be driven in the course of the rotating movement of the trigger body (20) and to delay the rotating movement of the trigger body (20). The trigger body (20) and the delay element (22) are arranged inside each other so that they constitute an outer wheel shaft-free wheel and an inner wheel shaft-free wheel. The two wheels have parallel geometric wheel axes and delimit a ring-like gap. At least one of the wheels is embodied wavy along its circumference on its surface facing the other one of the wheels with wave crests (20.1) and wave troughs (20.2). The wheels rest with areas of their surfaces facing each other on motion transfer bodies (24), which are located in the ring-like gap and are seated therein in a radially displaceable manner.
