ABSTRACT:
The disclosure relates to a tap or valve body (10) having a bore (11) to receive a tube which is locked in the bore by means of a collet form tube coupling (21) and is sealed to the bore by O-ring seals 17, 18. The collet is encircled by a plastics insert sleeve (22) located in a counter-bore (19) at the end of bore 11 and held therein by a spring ring (39) embedded in the sleeve. The insert sleeve has a tapered bore (27) which converges towards the end of the tape or valve body and with which resilient fingers (32) of the collet engage to be compressed around the tube by the convergent bore to grip and hold the tube in the body.
