Jain Irrigation's Compression fittings for Netafim Poly Tubing and Netafim Heavy Wall Dripperline (UniRam & Dripnet HWD) are easy to install.  A sharp edge inside the adapter grips the tubing and prevents it from slipping back, no clamps are needed.  The tubing is worked into the fitting with a circular motion.  For best results make a clean, straight cut in the tubing and do not crease the tubing as you work it into the fitting.
