The catches are loaded immediately at the back of the catch hooks 1 by a double armed approximately V-shaped spring comprising arms I! coiled at l3 intermediate the ends of the arms, the coiled part I3 being mounted on a riveted anchorage pin M on the face of the front plate 2. This Spring l2, l3, which replaces a W-shaped spring used in the past and arranged between the front and back plates 2, 3, is a very simple elastic device for the purpose and makes for the assembly of catch members in a much easier and expeditious manner because it is visible on the face of the front plate and can be manipulated easily by an assembler who can readily observe and ensure that the arms l2 of the spring are correctly engaging the catch hooks 1 before the boss 4, which covers the spring, is placed in position. The back of the boss 4 is provided with four clinching lugs l5 and the front plate 2 and back plate 3 abut with corresponding slits IE to receive the lugs which are clinched over the back plate, thus securing the plates and the boss strongly to both plates together and localising the catches in shaped spaces between the plates 2, 3.

It was not possible according to the old arrangement using a W-shaped spring, to employ more than two security lugs because the four limbs of the spring occupied a substantial space between the front and back plates and, if an attempt was made to use several clinching lugs some of them were found to foul some of the said limbs. The spring being external allows of the front and back plates to abut where the clinchings take place, so that double thickness metal of the casing can be used to secure the boss.

Constructionally the catch hooks normally project from the sides of the boss in line with the manually operated pressure members which project from the sides of the casing, inward pressure of said member simultaneously releasing the hasp.

Key locking mechanism, if such is provided, is

.4 preferably arranged on the casing remote from the boss.

What I claim is:

1. In fastenings of the kind described, a catch member comprising a casing formed of front and back plates rigidly connected and provided externally upon its front plate with a fixed hollow boss, having aligned openings therein, clinched onto said casing by clinchings which pass through abutting parts of both front and back plates, said boss being adapted for the engagement thereof by a hasp and a pair of aligned catches slidable within channels of the back plate and through said openings in the boss and extending as hooks one on each side of the boss and as outer ends through openings in each side of the casing, and a spring having two arms operating against the catches and which is disposed and concealed, within the hollow boss, substantially as described.

2. A catch member according to claim 1, and in which the arms of the spring are joined by a resilient coil used to anchor the spring to a peg fixed to the front plate of the casing substantially as described.

3. A catch member according to claim 1, and in which the arms of the spring operate against the catches immediately adjacent the catch hooks and supported against the face of the front plate of the casing substantially as described.
