ABSTRACT:
The device includes a connection tube in communication with a hole of a rail for fuel under pressure, the tube being provided with an end swelling. The device has a first threaded element fixed to the rail in a position corresponding to the hole and a second threaded element designed to engage the first threaded element. Removably set between the hole and the swelling is a seal element designed to form a seal both with the hole and with the swelling. The seal element is a body of revolution equipped with a passage along a pre-set axis, and includes two end noses designed to be inserted in the swelling and in the hole, respectively, and two tapered seal stretches.
