Claim:
A pipe clip comprising upper and lower clip members which are pivoted at one end to rotate with respect to each other for opening/closing the clip, the upper and lower clip members having inside surfaces defining upper and lower flange-receiving grooves adapted to receive and engage flanges of pipe sections, the upper and lower clip members forming, at an opposite end, upper and lower slots, a locking bar being fixed in the lower slot, characterized by comprising a U-shaped pull tab comprising two limbs having free ends fit over and pivoted to side walls of the upper slot, an abutting block fixed while rotating between the limbs of the pull tab and defining a through-hole through which a stem of a hook-on member extends, the hook-on member having a hooked end engaged with the locking bar, the stem having an end section extending beyond the abutting block and supporting a resilient element that is retained in position by a retention member and induces a biasing force on the pull tab, the retention member being movable with respect to the hook-on member to perform adjustment of the biasing force, wherein the end section of the stem of the hook-on member forms threading and the retention member forms an inner-threaded hole engaged with the threading of the hook-on member.
