Abstract

The invention relates to a casting (1) comprising a body having a wall (2) equipped with at least one slug (3) breakable by knocking so as to expose an orifice (4) through said wall (2) in place of said slug (3). The slug (3) is fixed to a resistant zone (5) of the wall (2) of the body by means of a breakable zone (6) surrounded by said resistant zone (5), the cross-section of this breakable zone (6), which connects the slug (3) to the resistant zone, being substantially reduced in relation to the cross-section of this resistant zone (5) and in relation to the cross-section of the slug (3). Moreover, the slug (3) is located completely outside the space defined by the two planes P1 and P2 between which the resistant zone (5) is inscribed. <IMAGE>
