ABSTRACT:
The disclosure relates to a tube coupling having a coupling body with a throughway open at one end to receive a tube and an open ended housing on the body projecting from one end through which a tube may extend into the throughway in the body. A collet is located in the housing having an annular part with resilient legs projecting towards the open end of the housing and terminating in jaws to engage an upset on the tube to hold the tube in the coupling body. The housing has an end region remote from its coupling body in which the collet jaws are constrained against expansion to release the tube and an intermediate region in which the ends may expand. A collet has arms projecting into and held in the throughway of the coupling body when a tube is present to restrain the collet so that the collet jaws are prevented from moving beyond the ends of the region of the housing to a position in which they could expand and release the tube.
