A lock member is provided in a housing movably between a standby position and a connected position. In a state wherein the lock member is locked in the standby position, when a pipe is inserted into an opening portion of the housing, the lock member is unlocked so as to be movable into the connected position; however, a tip portion of a detection stopper abuts against a flange portion of the pipe so as to prevent the lock member from moving into the connected position. Next, when the pipe is inserted further, and the flange portion passes the position of the detection stopper, the detection stopper moves into the connected position together with the lock member.

In a rapid coupling, a pipe nipple engages a through hole of a socket. A first annular groove provided on the pipe nipple serves to catch a locking ring provided in the socket, in order to lock the coupled condition. A sleeve is movable on the pipe nipple, the sleeve having an inner projection to be retained by the first annular groove of the pipe nipple in a pre-assembled condition. When the pipe nipple is inserted into the socket, the sleeve abuts the socket and is then moved along the pipe nipple until the inner projection is caught by a second annular groove if the coupling is properly locked. It the pipe nipple is not moved into the socket to such an extent that the locking ring is caught by the first annular groove, the second annular groove remains visible outside the sleeve to indicate the improper coupling condition.

A fluid dispensing apparatus includes an actuator body with an actuator and a valve stem coupled for movement with the actuator, and a fluid body having a fluid chamber capable of fluid communication with an outlet. The valve stem is adapted to extend from the actuator body into the fluid chamber for dispensing fluid from the fluid chamber through the outlet. A quick connect member is provided to selectively fully engage and disengage a first coupling element on the actuator body with a second coupling element on the fluid body, to connect and disconnect the actuator body and the fluid body with respect to each other. The quick connect member advantageously connects or disconnects these bodies without requiring disassembly or dismounting of the bodies from other elements associated with the fluid dispensing apparatus, with a simple manual movement such as a sliding linear continuous movement.

The invention relates to a part (2) for coaxial connection of two tubes (3 and 4), characterised in that it comprises two connection portions (6, 7) each provided with an area for receiving a connection element (31, 41) of each tube (3, 4), and in that the two connection portions (6, 7) are capable of sliding inside one another, between a separated position of the two portions (6, 7) and a tightened position of the two portions (6, 7) in which the two receiving areas form a closed contour and are capable of holding the connection elements (31, 41) together.

The present invention relates to a female cartridge coupling of the type suitable for being inserted into a support block, or manifold, which is connectable to a pressurized oil circuit on board the machine.

The female cartridge coupling in accordance with the present invention is characterized in that although it is configured to be inserted into a support block, it is suitable for being connected to Standard ISO 16028-compliant flush-face male couplings.

The cartridge in accordance with the present invention further comprises a system for mechanically locking the decompression valve which allows the connection of a male coupling.
