ABSTRACT:
The invention relates to an apparatus for detachably connecting two parts. It has a receiving part (1) which possesses a housing (3a). A lock (5a) which has a bevelled entrance (7a) is mounted in the housing (3a). A locking pin (9d) having a displacement part (12a) is used for locking or for latching with the lock (5a), which is kept pressed in the locking direction by a rubber ring (16). A spring or block acts against movement of the locking pin (arrow 57). An unlocking part (11a) is mounted on the shaft of the locking pin (9d) so that the said unlocking part can slide in the direction of movement (arrow 57). The locking pin (9d) carries a thrust plate (8) on its end facing away from the displacement part (12a). If pressure is exerted on this thrust plate, the displacement part (12a) initially interlocks with the lock (5a). When further pressure is exerted in the direction of movement arrow (57), the unlocking part (11a) forces the lock (5a) apart via the bevelled entrance (7a) and against the spring force of the rubber ring (15), at right angles to the direction of movement (57). The lock (5a) then jams at the displacer contour (17) of the unlocking part (11a). The connection can thus be parted again by pulling the locking pin (9d) out of the receiving part (1). In another embodiment, the lock (5k; 1) is held on the locking pin (9m: n) and the displacement part (12k:) is held on the housing 3n; m).
