A one-piece body attachment guides and secures the distal end of a recreational vehicle sewage discharge hose relative to the inlet of a relatively stationary sewage receptacle. Two vertical, spaced apart, parallel sidewalls and a rigidly connected end wall form a partially enclosed space that receives a horizontal portion of the hose, an immediately downstream ninety degree bent portion of the hose and an immediately downstream vertical straight portion of the hose. Abutments are rigid to the sidewalls to interfere with relative movement of the hose and attachment by being located above the bottom edge a distance substantially greater and/or substantially less than one-half the distance between the inner faces of the sidewalls, which are spaced apart a distance substantially equal to the diameter of the hose. The detents are wedge shaped for first compressing the adjacent walls of the hose as the hose is relatively moved between the sidewalls and then the detents permit the hose to expand, to securely hold the hose and attachment inter-connected. The detents are preferably spaced from the end wall a distance greater than the diameter of the hose plus the radius of the bent portion.
