A joint is provided for a double bladed paddle which allows for the angle between the blades to be adjusted relative to one another. The joint is formed from joining a female body recessed into a first shaft with a male body extending from a second shaft. The female body encloses a spring mechanism abutted by teeth of a crown with receiving grooves. The male body has protuberances which fit within the receiving grooves leading to the spring mechanism which when pushed in by the male body allows the protuberances to move past the receiving grooves and rotate to slot into the pockets formed between the teeth of the crown.
