I don't know if this has been mentioned, but have you by any chance had dirt on the male connectors or connector and tried to hook it up. You may have done this without even paying attention [happens to all of us at some time], but any way when you tried to hook it up maybe dirt has got behind the little bearings in the female part of the coupling and that little bit of dirt is holding you off.
The part of the coupling that pulls back has a small groove in it that lets the bearings drop back in it and that will allow the coupling to connect. If there is a little bit of trash of some kind in that groove that could be your problem.
I believe you are trying to hook up a snow thrower, is it a hydraulic motor that your are trying to hook up or is it the quick attach circuit? I was just curious.
I am going to try to describe something that I don't know if I can, but here goes anyway. You know when you are pulling a cork out of a bottle, you rock the cork back and forth but hold the bottle still or rock the bottle in the opposite direction, well those fittings are close fitting but sometimes you can do a little of that type rocking to help get it to slide up on or in the fitting. I surely hope this helps, if not I'll keep thinking. You might have to get some kind of mechanical device made up that will help you to seat the couplings, but there is a risk of damaging the coupling that way. If there is dirt in the male coupling that is holding you off you might be able to flush it out with wd40 using the straw and spraying back in the female coupling with the ring pulled back, spraying directly on those little bearings.
I try to inspect the connectors before connecting. I think that dirt in the connectors is not the issue. Yesterday I was able to reconnect the QA plate hoses without having to hold down the Aux lever. I do jiggle them a bit while pushing them together.
What I was doing: I had been using the snow thrower for two hours. I attempted to unattached the thrower and attache the power sweeper. The thrower has two hyd circuits: the main 1/2" PTO circuit drives the auger and the stage two motor; the chute activator is driven by the 1/4" Aux circuit. I had disconnected the Thrower Aux lines and was trying to reconnect QA plate hoses to the Aux circuit so I could unattach the Thrower. As I reported, we had to hold down the Aux lever and push the connectors on at the same time to effect a locked connection.
