Abstract
A coupling (1) for a shaft-end (2) having a square cross-section includes a front plate (6), a locking plate (7) and a rear plate (8) provided with square openings (9, 10, 11), in which the square shaft-end can be inserted. The locking plate can be rotated back and forth between an unlocked position (I), in which the square openings in the front plate, the rear plate and the locking plate coincide, and a locked position (II), in which the openings do not coincide. In the unlocked position the square shaft-end can be inserted through the coinciding square openings. Subsequently, the locking plate is rotated so that the shaft-end cannot be pulled out until the locking plate is returned into the unlocked position. The coupling can be used for easily interconnecting different types of parts, for example, applicable with exercise bicycles, bicycles, etc.
