ABSTRACT:
Surface drainage apparatus is provided comprising a channel body defining a drainage channel and a cover for the channel. A fixing means is provided for attachment of the cover to the channel body and comprises a first fixing element for attachment to the channel body and a complementary second fixing element for attachment to the cover. The first fixing element comprises a clamping spring defining a receiving opening and the second fixing element comprises a peg formed with an enlarged end that is a leading end for insertion of the peg into the clamping spring. The clamping spring and the peg are constructed so that the peg can be inserted into the receiving opening, thereby elastically deforming the spring, and retained therein after insertion in a direction substantially perpendicular to the plane of the cover.
