<p>The tank cap comprises a body (2) provided with a housing (3) capable of receiving a cylinder (7) connected in translation with the body but able to rotate under the action of an appropriate key. Means (V) of locking the cap on the end of a tank pipe (12), controlled by the rotation of the cylinder (7), comprise only one part (13) mounted in a rotary manner on the body (2) and which can be put into position on this body by a movement of translation in respect of a relative angular position of assembly/separation of the part (13) with respect to the body (2). The said part (13) comprises retaining means (R,16) on the pipe (12). The connection in translation of the part (13) and of the body (2) is obtained by a rotation, after the putting in position of the part (13), separating it from the angular position of assembly/separation. Means of angular positioning are provided on the cylinder and the body in order to allow the rotation of the cylinder only over an angular range from which the assembly/separation position mentioned above is excluded. <IMAGE></p> |
