<p>The disclosure relates to a latch collet pin (10) for the assembly of a collet (11), and seal (12) of a tube coupling in a tube coupling body. The collet and seal are pre-assembled on the pin. The pin has a bore (41) open to the seal from outside the coupling body through which a fluid under pressure may be directed to test the effectiveness of the seal after the collet/seal arrangement has been assembled in the tube coupling body, and prior to the pin being extracted. <IMAGE></p> |
