The projection I I of the male section is a turned '

A longitudinal opening 25 extends continuously
through the male section A from the outer end
of the ?tting I2 to the outer end of the projec

The extension 42 continues from what may be
termed the inner end of the stem 4| and in its
preferred form involves a pair of legs 50 which
diverge as they extend downwardly or from the
stem Ill so that their outer end portions bear
against the wall of the opening 25 in the projec- ‘
tion ll of the coupling section A. The extension
42 is formed of a material having suf?cient life or 10
