The seat face is adjoined, on its side oriented toward the portion of large diameter, by at least one face which is more markedly inclined relative to the longitudinal axis of the connection than the seat face, and on its side oriented toward the portion of small diameter, the seat face is adjoined by at least one face which is less markedly inclined relative to the longitudinal axis of the connection than the seat face.
