ABSTRACT:
A pipe clip includes upper and lower clip members that are pivoted at one end and form upper and lower slots with a locking bar fixed in the lower slot. The upper and lower clip members form upper and lower grooves for receiving and thus engaging flanges of pipe sections to be jointed therein. A U-shaped pull tab has two limbs fit over and pivoted to the upper slot. An abutting block is fixed while rotating between the limbs and defines a through hole through which a stem of a hook-on member extends by sliding. The hook-on member has a hooked end engaged with the locking bar. A helical spring is fit over the stem and retained between the abutting block and a nut engaging a threaded end of the stem. The clip is efficiently installed by engaging the hooked end of the hook-on member with the locking bar and can be secured and released by pushing/pulling the pull tab. The pull tab is configured to causes deformation of the spring to induce a torque against release of the pull tab from the secured position.
