This simple connector can join two 20 x 20 mm aluminum (or other) pipe ends together, either simple square pipes or I-type extrusions. It allows for 180° rotation and has a spring tensioned button for locking them in the straight position, a model without the lock is also provided. Extra: If the joint has to be straight while the lock is under tension, there is now a special variant of the left connector for that!
