Abstract:
A self-locking quick release coupler adapted to a groove adapter, the coupler comprising:a handle a first distal end of which is adapted to be secured to a side face of the groove adapter, the handle having a head formed on the first distal end thereof, the head being extendable into a side face of the groove adapter so as to secure a tube inserted into the groove adapter; a substantially Z-shaped lever partially extending through an aperture in the handle to be pivotably received in the handle, the lever having a hook formed on a first distal end of the lever to adapt to hook a pin of the groove adapter and a press formed on a second distal end of the lever and extending through said aperture; a spring a first end of which abuts an under face of the handle and a second end of which abuts an under face of the lever so as to provide a recoil movement to the lever; a first locking pin adapted to secure the handle to the groove adapter; and a second locking pin formed to secure the lever in the handle, whereby pivotable movement of the lever allows the hook of the lever to selectively hook the pin so as to secure the handle relative to the groove adapter.
