Patent ID: 7896402

Claim:
A spacer for spacing an internal aircraft pipe from an external aircraft pipe, wherein the spacer comprises: at least one closure; a pipe clamping structure having a diameter; at least one distance element, wherein the pipe clamping structure is adapted to enclose the internal pipe; wherein the at least one distance element is attached to the pipe clamping structure and wherein the at least one distance element is adapted to abut an internal wall of the external aircraft pipe and for holding the internal aircraft pipe at a specified distance to the external aircraft pipe; wherein the at least one closure is integrated into the at least one distance element such that the at least one distance element comprises two sections facing each other and forming a gap between the components of the spacer; wherein the gap has a width; wherein at least one distance element is adapted such that by pressing the two sections of the distance element together the width of the gap is changed and the diameter of the pipe clamping structure is determined; wherein one of the two sections of the distance element comprises a pin and the other of the two sections of the distance element comprises an eye; wherein the pin is provided with at least one first hook and the eye is provided with at least one second hook; wherein the pin enters the eye such that the at least one first and second hooks hook together to close the closure, the pin being of sufficient length to extend through said eye beyond said distance element; wherein the first hook and the second hook are flexible in order to allow them to slide over one another; wherein the depth up to which the pin penetrates the eye is adjustable for adapting the diameter of the clamping structure of the spacer; wherein the entire spacer is configured as a single part such that elements which are necessary for mounting are provided on the single part avoiding adding of additional components during the installation.
