ABSTRACT:
Surface drainage apparatus comprises a channel body defining a drainage channel with a cover defining apertures through which drainage can pass into the drainage channel. A fixing means for attachment of the cover to the channel body is provided and comprises a first fixing element for attachment to said channel body and a complementary second fixing element for attachment to said cover. The second fixing element comprises a bolt that is mounted in the cover so as to be capable of sliding into a locking position in the direction toward a long edge defined by said cover and back out of this locking position into an opened position. The first fixing element comprises a retaining means which when the bolt slides into the locking position engages with the bolt in such a way that said cover is retained on the channel body.
