Abstract

A technique for quick insert connecting tubular fluid pressure conduits into spaced ports having internal seal rings in a common side of a valve or block. A plastic spring lock member with apertures coinciding with the ports is disposed over the ports. The apertures are chamfered on a common side and slotted for permitting resilient expansion. The spring lock member is retained by a cover bolted to the block with clearance apertures over the ports. Upon insertion of a conduit with an annular convolution adjacent the end, the convolution cams against the chamfer expanding the slotted aperture permitting the convolution to snap through and the conduit to be retained in the port with the periphery of the conduit end contacting the internal seal ring.
