The beam has end terminals which can be connected to one another, such that one of the terminals is provided with front projections for guiding in vertical displacement of the other terminal, which has guides with a form which mates with the said projections, one of the terminals also having projecting lower arms to support the other terminal after it has been put into position, thus determining a single area of contact in order to permit disconnection of the supported terminal during dismantling, by turning on the said area of contact.

The invention claimed is: 1. A purlin beam with connectable terminals, comprising:a male terminal at one end and a female terminal at the other end, which can be connected to one another,wherein the female terminal is provided with front projections for guiding in vertical displacement of the male terminal, which has a pair of straight guides with a form which mates with the front projections, the female terminal also having projecting lower arms to support the male terminal after the male terminal has been put into position, thus determining a single area of contact in order to permit disconnection of the supported male terminal during dismantling, by turning on the said area of contact,wherein a central portion of the male terminal includes a single lower extension projecting in a longitudinal direction of the beam, the straight guides being formed on opposite lateral sides of the single lower extension and extending parallel to the longitudinal direction of the beam, the straight guides of the single lower extension being adapted to be nested between the front projections of the female terminal.
