I wouldn't worry about making the connections across the top permanent. Just use some long wire ties to fasten the cross pieces to the tops of the different trellises and then at the end of the year just cut the plastic ties and take down the cross pieces. The most important thing is to put in some diagonal supports driven into the ground and attached to several of the trellises. I had a whole trellis topple last year because I depended on the trellis holding upright just from being driven deeply into the ground. I now always put several diagonals on my long trellises but since yours are rather short I think one on each side of the bed with all of your individual trellises connected across the top would save you from the disaster of having them fall over. It is a lot easier to support the trellis now than once it starts leaning or after it falls. Below is a picture of one of my large trellises and you can see the diagonals that are attached with wire ties to the trellis.
