pvc pipe lock

I apologise if this has been done before an easer way I couldn’t find any thing about it in any searches or posts I have read and done I hope it is of some help to some one the total cost of clips to do 4 frames was £3.95 for 100 clips


This stops any twisting or separation of your pvc frames. you don’t have to glue any of the fittings to the pipe so you can take apart the frame and make other structures using every pipe and fitting. These are very easy to make I used the thick plastic strap that packs of house bricks come banded together with and 4.8mm x 9.6mm pot rivets (bigger headed rivets would be better but I couldn’t find any) bent 90degreese at the base. Just cut a 5in piece of the plastic strap drill a hole at one end the size of the rivet shank elongate the hole a bit by pulling on the strap once the drill has gone through. Bend the rivet to about 90degreese put the shank through the hole in the strap then rap a piece of duct tape around the shank of the rivet and the strap. Now bend the strap so the other end is in line with the head of the rivet (don’t let this end go past the head of the rivet as it doesn’t seem to work so well it can be a bit shorter though) the bend of the strap must be narrower than the with of the pipe so it is a V shape when you look inside the pipe not a U shape. Each one takes me about 30 seconds to make.


The hard part is drilling every pipe and fitting exactly the same so every pipe can fit in any fitting. I assembled the frame and laid it flat on the floor making sure every pipe was pushed all the way to every fitting then I used a small piece of paper aligned with the seem of the fitting and the front edge of the fitting I then put a pin hole in the paper in the middle and marked the pipe using a fine point fibre tipped pen. I then drilled both the fitting and pipe at the same time using a 5mm drill. I then used a big drill bit in reverse to counter sink the holes in the fittings only. You then just take the spring lock and slip it in side the pipe so the rivet goes through the hole make sure it moves in and out freely (some times the hole will need a very slight enlargement for variation of the rivet head) then just line up the rivet with the hole in the fitting depress rivet push pipe in to fitting and the rivet will lock in to the hole. To undo depress the rivet all the way in with thumb twist a bit then pull

    A great idea! But there is no place where I can find springy steel.

    This is plastic all though steel banding would also work. you can find it in all most any building site skip / dumpster or ask any building supplies store that sell bricks singly if you can have a piece out of there bin they are normally more than happy to let you take some. its more common than you think mono blocks, kerb stones, roof tiles, all have this type of banding.
    Good luck with your hunt

    Awesome! My snow shovel uses the same concept, wonder why I never thought of using it for my PVC structures.

    strapping free at B & Q warehouse ask at the builders Yard when you can buy the pipe and fittings with the rivets..
  • Scott Gallatin 4y

    Great Idea!
  • Anniiket 4y

    Great idea.. if anyone faces trouble finding rivets and springy steel, he can use simple nut bolts to keep the pipes in place..
  • Ivan Pinkul 4y

    Great idea. Thanks for sharing.

    good idea.. i just needed that!

    Hey guys, it may save time and money if " Single-End Spring-Leg Tubing Snap-Buttons" were used, instead of the DIY pipe lock. Can be purchased on line, or at large hardware stores.
  • Ed 2y

    What are single-end spring-leg tubing Snap-buttons?
  • Ben Stafford 2y

    Sounds like a awesome DIY solution for those that like to build various pvc contraptions. Mr-quad, have you thought of or have the capability of posting a how-to video on YouTube?
