This invention relates to a double pin holdment being such that the other limb of the anfast whichserves for holding together wood gular member forms a guide for the double parts, especially for toys and models of all pin by bearing firmly against one of the sides kinds, and has for its object a convenient conof one of the members to be connected tonecting member for wood parts of childrens gether by the double pin. 55

Accordin to the present invention the 10 double pin ioldfast consists of a double pin 60 which at the middle is firmly seated in one limb of an angular metal member so that the other limb of this member forms a guide for I the double pin by'bearing closely against one side of one of the wood parts to be connected 65 together by the double pin holdfast.
In the accompanying drawings Figures 1 .and 2 show the double pin holdfast in side elevation and in perspective, and Figure 3 shows a number of wood parts connected to- 7D gether by the double pin holdfast. The double pin a is secured at the middle in the centre of one limb b of an angular metal member or L-shaped member. When assembling Wood parts the second limb c of I 75 the angular member forms a secure guide for the double pin a as it bears firmly against one side of one of the two wood parts to be connected together. WVood parts connected together by double pin holdfasts as above described are firmly connected together thereby but can subsequently again be easily separated from one another. The limb b of the angular member in which the double pin a is secured prevents 85 the pin from penetrating too far into the wood.
I claim 1. A double pin holdfast for connecting together wood parts, particularly for toys and 90 models of all kinds, comprising an L-shaped member of metal, and a double ended pin secured in the centre of one of the limbs of the L-shaped member. 2. A double pin holdfast for connecting 95 together wood parts, particularly for toys and models of all kinds, comprising an angular member of metal and "a double ended pin secured at the middle in the centre of one of the limbs of the angular member, the arr-ange-
