A joint arrangement for joining first and second longitudinally aligned piling members, said joint arrangement comprising said first and second members and: at least one cantilevered resilient strut arranged to project from said first longitudinally aligned member in an inboard manner towards the axis of said first longitudinally aligned member or arranged to project from said second longitudinally aligned member in an outboard manner away from the axis of said second longitudinally aligned member ; said at least one cantilevered resilient strut comprising a proximal end attached to the member from which it projects and a distal end , wherein said at least one cantilevered resilient strut is resiliently biased such that at rest the distal end of said at least one cantilevered resilient strut is arranged to be laterally displaced away from said member to which it is attached; said distal end arranged to abut a complementary stop in/on the other member when said second member penetrates said first member , wherein said complementary stop is a recess in the other member and/or is a projection on the other member; wherein said at least one cantilevered resilient strut is a compression strut which acts to resist withdrawal of the second member via compression in the at least one cantilevered resilient strut ; wherein the at least one cantilevered resilient strut is formed from a sleeve that is attached to the first member or second member or is formed from the wall of the first member and/or second member creating a gap in the sleeve or in the wall of the member, respectively, which can accommodate the at least one cantilevered resilient strut when it is pushed towards the member on penetration of the second member into the first member . at least one cantilevered resilient strut arranged to project from said first longitudinally aligned member in an inboard manner towards the axis of said first longitudinally aligned member or arranged to project from said second longitudinally aligned member in an outboard manner away from the axis of said second longitudinally aligned member ; said at least one cantilevered resilient strut comprising a proximal end attached to the member from which it projects and a distal end , wherein said at least one cantilevered resilient strut is resiliently biased such that at rest the distal end of said at least one cantilevered resilient strut is arranged to be laterally displaced away from said member to which it is attached; said distal end arranged to abut a complementary stop in/on the other member when said second member penetrates said first member , wherein said complementary stop is a recess in the other member and/or is a projection on the other member; wherein said at least one cantilevered resilient strut is a compression strut which acts to resist withdrawal of the second member via compression in the at least one cantilevered resilient strut ; wherein the at least one cantilevered resilient strut is formed from a sleeve that is attached to the first member or second member or is formed from the wall of the first member and/or second member creating a gap in the sleeve or in the wall of the member, respectively, which can accommodate the at least one cantilevered resilient strut when it is pushed towards the member on penetration of the second member into the first member . <EOS>
