A self-retaining smooth bore insert employs a helical coil spring for retaining a fluid system component in a smooth bore. The spring comprises two connected helical coils. One coil is coiled around the component. The second coil has an engarged diameter which engages the wall of the smooth bore. An end portion of the second coil is engaged by an installation tool to contact the coil to permit installation.
