Abstract

The cap (1,20) grid cap or the cap portions of a cover like an inspection or water discharge well in the surface of a road or foot-path comprises at lease one such slot-like opening (18, 31) extending from its periphery that when applying an external force to a peripheral portion of the one cap portion, a resilient movement from the one cap portion with respect to the other one occurs in the plane of the cover.
