A modular conveyor , comprising a plurality of modules successive in a transport direction (P), each comprising a body part with a transport surface for transporting products thereon, which body part during use is hingedly coupled via a hinge pin to the body part of a successive module, wherein the successive modules are adjustable from an assembly position (I) in which the body parts of the modules cooperate to form a receiving space that allows insertion and exit of the hinge pin , to an operative position (II) in which the body parts of the modules cooperate to form a receiving space that retains the hinge pin , wherein: - the body part comprises a first hinge part , which cooperates with a correspondingly formed second hinge part of the successive module, - in the assembly position (I) the hinge pin has a first position (i) within one of the first and second hinge parts , and in the operative position (II) the hinge pin has a second position (ii) within that hinge part, in which the position of the hinge pin is displaceable transversely to its longitudinal axis (A), preferably in transport direction (P), - between the first (i) and the second position (ii) a passable barrier is arranged, - a hinge hole of a hinge loop of the second hinge part corresponds to the diameter of the hinge pin , - the successive modules are each provided at a front and rear with the correspondingly formed first and second hinge parts , wherein the transport surface is part of a transport blade portion of the body part that extends from the rear to the front of the module, and wherein the hinge parts are part of a hinge assembly portion of the body part located below the transport blade portion , characterized in that , - the successive modules are rotatable until their body parts are supported onto each other to displace the hinge pin through lever action of the second hinge part , - during displacement the hinge pin is forced to pass the passable barrier , which after passing restricts reverse displacement, such that the hinge pin is retained against displacement transversely to its longitudinal axis (A). - the body part comprises a first hinge part , which cooperates with a correspondingly formed second hinge part of the successive module, - in the assembly position (I) the hinge pin has a first position (i) within one of the first and second hinge parts , and in the operative position (II) the hinge pin has a second position (ii) within that hinge part, in which the position of the hinge pin is displaceable transversely to its longitudinal axis (A), preferably in transport direction (P), - between the first (i) and the second position (ii) a passable barrier is arranged, - a hinge hole of a hinge loop of the second hinge part corresponds to the diameter of the hinge pin , - the successive modules are each provided at a front and rear with the correspondingly formed first and second hinge parts , wherein the transport surface is part of a transport blade portion of the body part that extends from the rear to the front of the module, and wherein the hinge parts are part of a hinge assembly portion of the body part located below the transport blade portion , characterized in that , - the successive modules are rotatable until their body parts are supported onto each other to displace the hinge pin through lever action of the second hinge part , - during displacement the hinge pin is forced to pass the passable barrier , which after passing restricts reverse displacement, such that the hinge pin is retained against displacement transversely to its longitudinal axis (A). <EOS>
