Abstract
A connector (30) in a network of lubrication pipes (31, 32, 33) is provided with a valve (45) that automatically closes off the connector (30) whenever one of the pipes is withdrawn following an incident. Lubricant leaks are thus avoided. The valve plug is cylindrical-conical (46, 47) and it is fitted with a needle (48).
