Abstract

The invention relates to a cover for a manhole covering, comprising at least one locking element (16, 18) that is provided on the cover (10). Said locking element has at least one spring-loaded arm (18) with an engagement section (18a) that can engage with part (6) of a frame (1). The invention is characterised in that the spring-loaded arm (18) is positioned in such a way that its engagement section (18a) can be displaced relative to the neighbouring section of the periphery (10a) of the cover (10) at an angle that is smaller than a right angle.
