the female portion 18 until retention collar 16 is seated between end face 62 and axial face 46 see fig7 as shown in fig8 retainer member 24 is preassemble onto end portion 14 of male member 12 by inserting mating portion 14 into retainer member 24 such that annular retention collar 16 first engages angled face 64 and deflects locking beam 56 radially outward allowing retention collar 14 to pass and be seated axially between axial face 46 and end face 62 thereafter male member 12 carrying preassembled retainer member 24 is driven against the end face 19 of the female conduit causing end face 60 of locking beam 54 to engage annular wall portion 52 and be deflected radially inward allowing the retainer and male member to suddenly pass into female portion 18 until the channel 50 seats in annular wall portion 52 in either assembly the male and female conduits are capable of rotational swivelable movement relative to one another and removability is possible by depressing end portions 51 radially inward whereby retainer 24 may be released from the receptacle or by coaxial insertion of a blade not shown between the outer periphery of male member 12 and inner surface of locking beam 56 accordingly there is provided a retainer which resists insertion of the mating male portion of the connection until the installer applies enough push in force to result in the male rapidly traveling completely and locking when the retainer resistance is overcome locking beam 54 produces the same effect if the retainer is mounted and locked on the male portion and both are being installed in the female.
