RCA connectors-how to tighten them up.

Thanks Cleeds, I am probably mangling the terminology.

As far as cheap connectors, they are AQ sky pigtails on my Vandy crossover. I have tried them on different equipment, but they just seem loose compared to my other cables. 
I think they were used on some nonstandard rca jack at some point.

Looking inside the female 'jack', there are 4 small tabs along the inside of the housing. I thought those might be responsible for snugging the cable.

At worst, I will send them back to Vandy, the need the batteries replaced soon.

You're right. I give that advice to others. I should have taken it myself.

Thanks Ken, I never would have found that.
