Abstract

The aim of the invention is to provide an easy fastening of a tubular supply or a vertical pipe in a bottom covering of a cooling chamber for pistons of internal combustion engines, e.g. in a circular covering of a cooling channel of an articulated-skirt piston. To this end, the vertical tube or the tubular supply is clipped into the bottom covering or is fastened thereto by a detent connection.
