The runner further comprises at least one shoe ( 10 ) received in the first compartment ( 8 ) and mounted to slide relative to one of the rails, namely the male rail or the female rail, the shoe comprising at least a first rigid portion ( 11 ) having a shape substantially complementary to the shape of the first compartment in order to offer contact zones for contact with the male rail and with the female rail when the runner is subjected to deformation in a first direction.
