Connecting device for quickly and releasably interconnecting two bodies

Abstract

A connecting device for releasably interconnecting first and second bodies includes a housing which can be applied to a holding means, and a locking pin having a locking head which can be turned to and fro between a starting position in which the locking head can be introduced into a receiving opening in the holding means and a locking position in which the locking head engages under a support portion formed by edge regions of the receiving opening. A stressing spring arrangement is operable to urge the locking pin from an axially advanced position in the starting position of the device into an axially withdrawn position in the locking position, in which the pressure contact surface of the locking head is pressed by the spring arrangement against the support portion of the holding means. The housing has a guide surface against which a running surface of the locking pin is pressed, with increasing stressing of the spring arrangement, in the transition from the starting position into the locking position, without the pressure contact surface of the locking head initially contacting the support portion against which it is pressed only at the end of the rotary movement.
