ABSTRACT:
The disclosure relates to a cylindrical collet for a tube coupling body, the collet having at least one arm of arcuate cross section which is free to flex radially under the action of an encircling tapered cam surface in the tube coupling body. The arm has a projecting tooth on its radially inner side having an inner edge to engage and grip a tube extending through the collet. The inner edge of the tooth extends linearly transversely of the arm to engage the tube tangentially and, with pressure from said cam surface, to bite into the surface of the tube.
