A bracket is provided for a bow. The bracket connects a header and a jamb. The bracket has a pair of end faces disposed generally orthogonal to one another with one end face abutting the header and the other abutting the jamb; and a pair of tongues extending from said end faces for engagement with end sockets formed in the ends of the header and jamb. The bracket is formed in two pieces arranged face to face along a medial plane extending between the end faces and held together by a fastener extending through a radial web that connects the end faces. Each said tongue is provided with at least one aperture therethrough alignable with similar apertures formed through the end sockets of the headers and jambs whereby a fastener can pass through the aligned apertures in a socket having a tongue inserted therein and fastened, to secure the components to one another.
