In a securing element (10) for connecting two parts, in particular for a screw connection, the securing element is ring-shaped. The securing element has an outer profile (11) along the outer diameter and an inner profile (12) along the inner diameter. The outer profile (11) and the inner profile (12) are both formed by a plurality of profile units. The number of profile units of the outer profile and the number of profile units of the inner profile correspond to the number of graduation marks at different scales according to the principle of a vernier scale, the number of profile units of the outer profile (11) differing by at least 1 from the number of profile units of the inner profile (12). In precisely one position, a profile unit of the outer profile (11; 111; 1011) is exactly opposite a profile unit of the inner profile (12; 112). |
