Abstract
A coupling which includes an inner and outer part is used to connect two coupled members. The inner part has a cylindrical outer wall and the outer part has a recess around which is a cylindrical inner wall, the recess fitting over the inner part so that the outer wall faces the inner wall. A gliding groove in one wall faces an annular locking member on the other wall, and the annular locking member fits into the groove to lock the inner and outer parts in the mounted position. The gliding groove is shaped to glide over the annular locking member during mounting and dismounting. To prevent the inner and outer part from rotating relative to each other, a key on one part fits into a keyway in the other part. The two parts may be connected by applying a slight compressive force so that the gliding groove glides over the annular locking means into the mounted position. Similarly, a slight tensile force may be applied for dismounting. One of the parts may be made of a hard material, while the other part is made of a softer material which will absorb damage in case of impact between the two parts.
