A seal requiring no compression type clamp is provided for a drain nipple-hose assembly having a tubular tapered drain nipple projecting from a structure to be drained and a corrugated hose for placing over the drain nipple. The seal includes a hollow flexible inner sleeve and a hollow outer sleeve which is longer than the outer sleeve. The seal also includes an annular wall member which joins an end of the inner sleeve to an end of the outer sleeve. The inner sleeve is stretched over the drain nipple between the drain nipple and the hose so that the inner sleeve sealingly engages the drain nipple and the hose. The outer sleeve surrounds an end of the hose. The wall member has a curved sectional shape, which is concave in a direction in which the drain nipple opens to the hose.
