Trench drains are hollow or grid-like bodies which can be installed in the ground and are intended to receive precipitated surface water and slowly dissipate it into the ground or to store the water. These hollow or grid-like bodies are constructed from individual drainage bodies which must be firmly connected together. Drainage body connecting elements are proposed for connecting drainage bodies, which comprise two pegs which are connected via a web and can each be inserted in a receiving orifice of a drainage body so the two drainage bodies can be connected together via the web.

Drainage body connecting element

The invention concerns a cover element for covering an opening in an in particular horizontal surface of a drainage body, with an edge region which is configured to support the cover element on the drainage body, and with a cover region which has a grid-like or perforated structure with supporting elements. It is distinguished in that the supporting elements have a thickness increasing in the vertical direction starting from the edge region in the direction of the regions remote from the edge, such that the cover element has a substantially plano-convex outer contour.
