ABSTRACT:
The disclosure relates to double ended tube coupling (10) having a coupling body (11) with the throughway (12) through which a tube can pass. Collets (16) are located in the open ends of the throughway having resilient arms to engage the tube and tapered internal cam surface (15) are formed adjacent the open ends of the throughway to engage the arms of the collets to cause the collet to lock tubes extending into the ends of the coupling body in the body. Midway along the throughway in the coupling body there are four resilient arms (25) moulded integrally with the wall of the coupling body and inclined towards one end of the coupling body to provide end stops (26) to limit the insertion of a tube into the coupling body from that one end but to permit a tube to pass through the coupling body when inserted from the other. Thus the coupling body can be slid over an end part of one tube, a second tube moved into alignment with the first tube and the coupling body then return to bridge the tubes with the end stops of the resilient arms locating the coupling body between the two tubes.
