An inexpensive and reliable security bar that may be easily and quickly assembled between structural supports of a guarded area to prevent entry into the area. The present security bar comprises first and second elongated bar members, one end of each of which is respectively installed into a structural support. The security bar members are substantially aligned with one another across the entrance to the guarded area, so that a small gap is formed between the second ends thereof. A hollow coupling sleeve is positioned over the gap, and a dowel or pin is inserted through a hole in the sleeve and into the gap between the bar members. Accordingly, when in the assembled relationship, the sleeve and pin cooperate to inhibit the lateral and angular displacement of the bar members, whereby to prevent removal of the security bar from the guarded area after installation between the structural supports thereof.
