ABSTRACT:
A fuel distributor pipe (1) which can be subjected to a high internal pressure loading includes at least one connecting arrangement (12) serving for releasably connecting a branch pipe (3) and having a connecting bore (5) which extends radially through the wall of the distributor pipe and which has an inner portion (8) and an adjoining, outer portion (9) which enlarges in a hollow-conical configuration, a screwthreaded socket (12) which is connected to the distributor pipe and whose internal bore (15) extending therethrough continues the connecting bore and serves to receive the branch pipe, and a pressing element (22) having a pressure surface (23) which, when the pressing element is screwed on to a counter-pressure surface (24) provided on a thickened portion (25) of the branch pipe, exerts a force by which a counter-sealing surface (16) of the branch pipe is pressed against the conical wall (18) of the outer portion of the connecting bore. To simplify manufacture while at the same time guaranteeing a sealing connecting which can withstand the high operating pressures, it is provided that the end of the screwthreaded socket, which is towards the distributor pipe, is applied at the end to the outside of the distributor pipe and is connected thereto.
