Date Mar. 14, 1996A coupling arrangement comprising male and female pipe coupling parts. The arrangement comprises a body which can be connected to the male part, with two elongate elements which are connected by a ring acting as a radial spring and which define between themselves a slit aperture, which is covered by a strip of non-transparent, flexible material which comprises a transparent window or a through hole. One end of the body is formed with a radially projecting flange, which is adapted to engage behind a radially inwardly directed flange on the female part, defining a locking position. There is an indicator member which is axially displaceable within the body and adapted such that it moved by the female part against the effect of a spring member. In the locking position, a symbol on the indicator member, which symbol indicates this locking position, is visible in the window. |
