A drainage channel comprising a channel body which is U-shaped in cross-section and defines a concave base and integrally formed opposing first and second vertically spaced-apart side walls, the first and second side walls including respective crowns formed in upper free ends of the side walls. The upper free end of the side walls define a predetermined thickness between respective inner side wall surfaces and outer sidewall surfaces. The outer surfaces of the side walls define an elongate detent spaced below the upper free ends of the first and second side walls and extending along at least part of the length of the channel body and defining an area of reduced thickness below the relatively thicker free ends of the first and second side walls. A coping encloses the crown of a respective side of the channel body. The coping includes an inner leg for resting against the inner side wall surfaces of the channel and an outer leg for resting against the outer side wall surfaces of the channel. The outer leg has an elongate rib of enlarged dimension on a free end of the outer leg for being received by means of a snap fit over the relatively thick free end of the side wall into the detent.

A drainage channel comprising: (a) a channel body adapted to be set into a surface, said channel being U-shaped in cross-section and having a concave base and integrally formed opposing first and second vertically spaced-apart side walls terminating in upper free ends; (b) crowns formed in an upper portion of each of said side walls, said crowns comprising the upper free ends of the side walls, said upper free ends being of a predetermined thickness between respective inner side wall surfaces and outer side walls surfaces and an elongate area of lesser thickness than said predetermined thickness in said outer side wall surfaces, said elongate area being spaced below the upper free ends of the first and second side walls and extending along at least part of the length of the outer surface of the channel body side walls; and (c) a coping for enclosing the crown of a respective side wall of the channel body, the coping including a downwardly facing inner leg for resting against the inner side wall surfaces of the channel, a downwardly facing outer leg for resting against the outer side wall surfaces of the channel and a member connecting upper portions of said inner and outer legs for covering the upper free end side wall surfaces of the channel body, said outer leg terminating in a free end comprising an elongate rib of enlarged dimension, said rib being adapted for being received by said elongate area of reduced thickness of said side wall whereby said coping can be anchored to said side wall by means of a snap fit onto said crown of said wall.
