an unattached tab aligned with a second face of the rod that is opposite to the first face; a substantially diagonal bridge connecting the flat tab and the unattached tab, wherein the angle between the attached tab and the diagonal bridge is greater than 90°; and a button located on the flat tab, wherein the button protrudes from the distal end of the rod when the spring is normally open, and wherein the button is configured to engage with a corresponding hole in a pipe. ## Claims ### Claim 1 A spring for connecting a pipe to a rod, the spring comprising: a flat tab attached to a rod, wherein the flat tab is aligned with a first face of the rod; an unattached tab aligned with a second face of the rod that is opposite to the first face; a substantially diagonal bridge connecting the flat tab and the unattached tab, wherein the angle between the attached tab and the diagonal bridge is greater than 90°; and a button located on the flat tab, wherein the button protrudes from the distal end of the rod when the spring is normally open, and wherein the button is configured to engage with a corresponding hole in a pipe. ### Claim 2 (depends on 1) The spring of claim 1, wherein the unattached tab comprises an outwardly convex end and an uplifted tip configured to press against the inner wall of the pipe, wherein the outwardly convex end protrudes from the rod when the spring is normally open, and wherein the spring is configured to be compressed such that the button does not protrude from the distal end of the rod and the outwardly convex end does not protrude from the rod. ### Claim 3 (depends on 1) The system of claim 1, wherein the attached flat tab is attached to a distal portion of the distal end of the rod. ### Claim 4 (depends on 1) The system of claim 1, wherein the attached flat tab is attached to a proximal portion of the distal end of the rod. ### Claim 5 (depends on 1) The spring of claim 1, wherein the button has a gradient in at least a proximal or a distal face. ### Claim 6 (depends on 1) The spring of claim 1, wherein the unattached tab is a flat tab that is aligned with the rod. ### Claim 7 (depends on 6) The spring of claim 6, further comprising a second protruding button located on the unattached tab, wherein the second protruding button is configured to engage with a second corresponding hole in the pipe. ### Claim 8 (depends on 7) The spring of claim 7, wherein the second button has a gradient in at least a proximal or a distal face. ### Claim 9 (depends on 6) The spring of claim 6, wherein the attached flat tab and the unattached flat tab are parallel to each other. ### Claim 10 An S-shaped spring connector for attaching a pipe to a rod, the S-shaped spring connector comprising: an S-shaped leaf spring comprising: an attached flat tab disposed with a protruding button, wherein the button is configured to engage with a corresponding hole in a pipe, an unattached tab disposed with a convex end, and a substantially diagonal bridge connecting the attached flat tab to the unattached tab, wherein the angle between the attached tab and the diagonal bridge is greater than 90°; a rod comprising a distally-disposed elongated cavity, wherein the attached tab is attached to the rod such that the S-shaped leaf spring is enclosed in the elongated cavity and the attached flat tab is aligned with a first face of the rod and the unattached tab is aligned with a second face of the rod that is opposite to the first face, wherein the protruding button is exposed at the first face of the cavity and the convex end is disposed at the second face of the cavity, and wherein when the S-shaped leaf spring is in a normally open configuration, the button and the convex end protrude outwards from the distal end of the rod.
