Snap-on cover of the trunking and chute provided with such a cover snap-on

摘要

A cover the snap-fastening of the chute 10 comprises an elongated wall 11 in a longitudinal direction is bordered by two lateral flanges 12 and 13, at least one of which is shaped so as to be assembled on a wing of the trunking base section and is provided with a plurality of areas of weakness 16 periodically spaced apart in the longitudinal direction. The longitudinal pitch of some of these primers is advantageously equal to the pitch of the slots which may be made in the flanges of a trunking base section on which the cover is snap-fastened.
