The invention relates to an angular joint element for metal carpentry. This angular joint element facilitates the assembly at its corner portions of tubular profiles forming side uprights (5) and crosspieces (6) for the formation of simple or multiple frames for building. The angular joint element (10) has two hollow branches (1, 2) with a cross-section equivalent to that of the upright and crosspiece profiles (5, 6), such that the ends of said branches are arranged end-to-end with respective ends of said uprights and crosspieces, forming a corner of the frame and being joined to said profiles (5, 6) by welding or adhesion with the intervention of inner support cores (7, 8) which are introduced in the openings of respective end-to-end members (1, 2, 5, 6) and can provide a temporary linking.
