ABSTRACT:
A joining device for joining adjacent frame members and in particular for joining picture frame members has at least two connected limbs having a trapezoidal cross-section with a first angle between the limbs. The first angle corresponds to the angle between adjacent frame members. The frame members have mitred ends and are provided with a recess, also having a trapezoidal cross-section, into which the limbs can be inserted, which results in abutment and joining of respective frame members. The trapezoidal shape of the joining device provides resistance to twisting of the frame members and also ensures a firm frictional engagement to hold the mitred ends of the frame members together. The joining device may have a second angle between the longitudinal axes of the limbs which results in the front surface edges of the mitred ends being forced together so as to make a less obvious join line between frame members.
