A telescopically adjustable support brace includes a first member and a second member operably moveable with respect to the first member in a telescopic manner. The first and second members are adapted to be positioned across two objects for maintaining a fixed distance therebetween. A quick-clamping device includes a collar moveably engaged in the first member and a quick-release device for selectively clutching the collar to the second member, and when the collar is clutched to the second member, the second member is adapted to be moved with respect to the first member by the collar. Further, an adjusting device is operable to move the collar with respect to the first member and the collar is thereafter adapted to move the second member with respect to the first member.
