Sounds like the connector does not have enough friction to keep it in there and/or it's really hot out causing the plastic to expand creating space for the connector to slip out. You can stop that by drilling holes and adding rivets. You can also try sanding the connector and the inside of the tubing with medium grit sand paper to add more friction, however that is just the side effect of a friction connected hoop. Also your hoop should be able to coil down, you have to pull the ends apart at the connection point and then coil the hoop down to re-connection the ends.
Adhesives are a quick fix but wont solve the problem permanently.
You might try wrapping plumber's tape (very cheap!) around the insert and then reconnecting it. If you coil it down many times, you might have to replace the tape every once in awhile. The very best solution would be to get yourself a pop-rivet --which is going to keep it from coiling down--unless you also add a travel connector. Try Spinsterz....?
yeah! I think you would need a drill with 1/8 bit and a rivet gun with aluminum rivets that are 1/8 inch diameter. I can't speak from experience so I think you could find some tutorials on youtube. I know hoopsupplies.com sells a kit with directions. Hopefully someone can chime in with this to confirm :D
the drill bit size depends on the size of the rivet, you can get tiny ones (1/16 diameter) that wont through off your hooping. They are made to fit flush with the flat surface but rivets are kind of rounded so it's not completely flat, it's not really noticeably. If you feel it's annoying when hooping you can sand down the rivet, but be careful with how much you sand down.
*here is an ebay seller with good ratings. It's for a rivet gun and 60 rivets, pretty good price and a U.S.A seller.I have this style of rivet gun works great. Any local hardware store will have a rivet gun and rivets nut sure about local prices though.
If you want to be able to still coil it down, I suggest using a snap button.
You can buy them here:
You'd want to get the small sized button
[I used snap buttons from this site to make the collapsible hoop in my profile picture]
I haven't read down yet to see what others had said, but I ahve that issue with my polypros, I d breaks a lot and it just popped apart...I even keep it tapd, and still...it pops apart. I am invsesting in pop rivets to hold it. My first polypro was like that, but all the ones I made thus far are friction ( I don't sell them, esp not with them exploding open!! haha, but I make a bunch to play with, even hand hooping sometimes I open them!)
I seem to have to same prob with all my friction fit polypros..it's like the connection piece just isn't quite big enough or something. Mine popped open for the first time the other day with tape on the connection and I was like "O.O" I think rivets are the only really good way to close up a polypro!
If your friction fit isn't staying, you should let the manufacturer know and they may be willing to send you new connectors that are longer. We've sold a lot of friction fit polypro and have only had a couple that were too loose, we fixed them with longer connectors.
I'd contact Lara and Drew at Superhooper to see what they say. They might suggest that you sand the insert a little, which would make it a little tighter, maybe enough. Give them the chance to help you out, they might even send you a new insert or something........
I have not heard of a polypro hoop that is not friction connection and without rivets :/. Glues and adhesives are for only a short term fix. My only guess is trying to melt the connector to the inside of the hoop.
